Hakkaisan: A Complete History—A Century of 'Sake You Never Tire of Drinking' Born at the Foot of the Echigo Sanzan

The spring water of the sacred Mt. Hakkai, the climate of heavy snow, and a singular philosophy: 'Make ordinary sake of the highest quality.' This is a comprehensive look at the trajectory of over a century, from the founding of a single brewery in Minami-Uonuma, Niigata, to its transformation into a synonym for local sake and eventually a comprehensive brewing enterprise dedicated to 'rice, koji, and fermentation.'

Prologue—What a Single Bottle of Sake Carries

Minami-Uonuma City, Niigata Prefecture. The brewery stands at the foot of Mt. Hakkai, one of the Echigo Sanzan, a sacred mountain that has long been a site of worship. Today, the 'Hakkaisan' brand is known nationwide as a synonym for local sake and is often spoken of as a symbolic presence of Niigata sake, which is prized for its clean, dry finish. However, the reality behind that fame is often misunderstood in the marketplace.

'Hakkaisan' is not a product of so-called ginjo-supremacy. Rather, its core lies in the humble and honest idea of polishing ordinary sake for everyday drinking with the same effort and technology as ginjo. Refusing to be consumed as a 'phantom sake' that fuels scarcity, the company has viewed stable supply as a corporate responsibility, maintaining a balance between price and quality. In an era dominated by temporary frenzies, this stance was, if anything, heretical in the sake industry.

A century of history is by no means long in the context of the sake industry as a whole. It was founded in 1922, during the Taisho era. Among the many long-established breweries dating back to the Edo period, Hakkaisan Brewery was clearly a latecomer, and it was this awareness that always kept the company on the side of the challenger. This article carefully traces the philosophy the brewery has carried, as well as the climate, people, technology, and business development that supported it, from its pre-founding history to the present. How did a single bottle of sake become a philosophy, and how did that philosophy shape the culture of a comprehensive brewing enterprise? The complete history is recorded here.

Tracing the history of a single company is the work of deciphering the countless choices it has made as a single thread. Why did Hakkaisan Brewery abolish discounting? Why did it refuse to become a 'phantom sake'? Why did it continue to limit its brand to sake while venturing into businesses other than sake? These choices, which seem disparate at first glance, are, when traced, connected by one consistent philosophy. What was that philosophy? Clarifying that is the purpose of this article.

Chapter 1: The Sacred Peak—The Weight of the Name 'Hakkaisan'

Sake is a product of the land. Sake, in particular, is established upon the immutable natural conditions of rice, water, and climate. To understand Hakkaisan, one must first understand the mountain from which it takes its name and the land of Minami-Uonuma.

Mt. Hakkai is a group of rocky peaks towering over Minami-Uonuma City, Niigata Prefecture. Its highest peak is Mt. Nyudo, at an altitude of 1,778 meters. Together with Mt. Echigo-Komagatake (2,003 meters) and Mt. Nakanodake (2,085 meters), it is collectively known as the Echigo Sanzan, or Uonuma Sanzan, and the entire area is designated as the Echigo Sanzan-Tadami Quasi-National Park. Although its altitude does not reach that of the high peaks of the Japanese Alps, the rocky ridge zone at the summit, called the Yatsumine, shows a rugged appearance with a series of near-vertical chain sections, which has attracted climbers since ancient times.

This mountain was not merely an object of scenery. Mt. Hakkai is a mountain of ascetic training that has been revered as a sacred mountain since ancient times. Minami-Uonuma, surrounded by mountains on all four sides, was a land equipped with the conditions for a sacred site of mountain worship, and it was a region where Shugendo, symbolized by the yamabushi (mountain ascetics), permeated early on. The original faith in Mt. Hakkai is thought to have begun with a simple mountain worship in which the water-distributing gods (Mikumari-no-kami) and crop gods who protect agricultural products reside in the mountain. People living at the foot of the mountain did not dare to enter it, but instead set up torii gates and shrines in the villages to worship and hold rituals for the mountain from afar. Eventually, the mountain asceticism of Yoshino and Kumano and the sacred mountain worship of the Hokuriku and Kanto regions were superimposed on it, and the mountain worship of Minami-Uonuma showed a rich expansion. The Hakkaisan Son Shrine was enshrined as a village shrine, and that faith has been passed down to this day.

Bearing the name of a sacred peak means accepting both the blessings and the awe of that land. When Hakkaisan Brewery chose the name 'Hakkaisan' for its brand, it contained respect for the nature of this land itself. What the water-distributing god governs is water, which is the foundation of agricultural production. And sake, too, is born from the blessings of water and rice. Mountain worship and sake brewing were continuous activities in this land. The name Hakkaisan was not just a trademark, but a name that carried the nature and faith of the land.

Chapter 2: Climate—A Land God Prepared for Sake

Minami-Uonuma City is located in the southeastern part of Niigata Prefecture and is known as one of the heaviest snowfall areas in the country. In winter, it is covered with several meters of snow, and a state of low temperature and high humidity continues for a long time. This environment suppresses the growth of bacteria and is suitable for fermenting moromi slowly at low temperatures, which becomes a condition for producing sake with a fine, clean quality. In exchange for the inconveniences of the snowy country, nature prepared an ideal stage for sake brewing. The anecdote that a sake brewer who once visited this place commented that it was a land that God had prepared as if for making sake is something the company itself often cites.

For the brewing water, 'Raiden-sama no Shimizu,' a spring water that gushes from the middle of Mt. Hakkai, is used. This is extremely soft, ultra-soft water, and because fermentation proceeds gently, it becomes a sake with a soft and smooth mouthfeel. Soft water has weak fermentation power and increases the difficulty of sake brewing, but if handled carefully, it brings a clean and delicate taste. In 1985, this spring water was designated as one of the famous waters of Niigata Prefecture. In talking about the sake quality of Hakkaisan Brewery, the existence of this water is decisive.

Rice is also a blessing of this land. Uonuma is famous nationwide as one of the leading rice-producing areas in Japan, and its climate is also suitable for the cultivation of sake rice. The abundant snowmelt water brought by heavy snow and the temperature difference between day and night nurture high-quality rice. Furthermore, as a lineage of people who carry out sake brewing, there is the tradition of the Echigo Toji. The Echigo Toji is one of the three major Toji groups in Japan, mentioned alongside the Tanba Toji and Nanbu Toji, and is a group that has passed on techniques to breweries in various places as seasonal workers from deep snowy farming villages. This Toji culture, polished as a livelihood during the farming off-season, was inseparable from life in the snowy country.

Water, rice, climate, people. The foundation of Hakkaisan's sake brewing lies where the serious and tenacious temperament of the Uonuma people and these blessings are combined. Hakkaisan Brewery has consistently spoken of these four blessings as its greatest assets. Accepting the climate as a given condition and brewing sake that is worthy of it—this humble stance flows at the root of the company's sake brewing philosophy.

Chapter 3: Founding—The Ambition of 'Industry for the Region'

Hakkaisan Brewery was founded in 1922 (the 11th year of the Taisho era). The first president, Koichi Nagumo, began brewing sake in Nagamori, Jonai-mura, Muikamachi, which corresponds to the current Minami-Uonuma City. This is the starting point of the history of 'Hakkaisan'.

What is noteworthy is that Koichi was not just a sake brewer. His interest was not limited to the management of one brewery, but in regional development for the entire Minami-Uonuma area. In addition to the sake brewery, he built silk mills and other facilities one after another, trying to build a foundation for employment and the economy in this land, which was deep in snow and lacked industry. Hakkaisan Brewery was one of the businesses born from that ambition. The founding motive of 'industry for the region' was also a distant foreshadowing of how the later Hakkaisan would expand its business to regional contributions such as the operation of tourist facilities, the dissemination of food culture, and the creation of employment.

However, for a while after its founding, Hakkaisan Brewery was by no means smooth sailing. Until the first half of the 1950s, the company was just a small, near-unknown brewery that brewed a very small amount of sake. It would take a long time of struggle before this sake, which bore the name of a sacred peak, would make its name known nationwide. Being a latecomer, small in scale, and lacking name recognition—the severity of that starting point became the origin that shaped the corporate culture of Hakkaisan Brewery. The story of the brewery that would stand at the pinnacle of local sake did not begin from favorable conditions.

Chapter 4: The Five Comrades—Rebuilding from Negative

The first decisive turning point in the history of Hakkaisan Brewery came in 1953 (Showa 28). That year, the founder, Koichi Nagumo, passed away, and his fourth son, Kazuo Nagumo, took over the business at the age of just twenty-five.

The management situation Kazuo inherited was severe. At the time, production was less than 300 koku, and on the books, debts exceeded assets—a start from effectively negative territory. It was a precarious situation where it would not have been surprising if the brewery had collapsed at any moment; the young manager in his mid-twenties had to embark on a reconstruction.

Supporting Kazuo at this time were a small group of comrades who would later be known as the "Five Comrades." Yoshigoro Tomidokoro, who displayed great talent in accounting and fundraising; Takao Maruyama, who supported the manufacturing department, including bottling; and Haruo Takahama, who joined the brewery as a Toji (master brewer) in 1958 and established the fundamental quality of Hakkaisan sake. Furthermore, Kazuo's wife, Ai, who had married into the family from a wealthy farming household in Wajima Village, Shimazaki, took on the role of entertaining business partners with her own home cooking, warming the human relationships of the trade. Everyone was in their twenties at the time.

What these five shared was a single ambition: to brew good, light, and balanced sake that one would never tire of drinking, and to develop the company through that. They believed in the role of sake as a drink to accompany meals, and they devoted themselves wholeheartedly to realizing that ideal. A brewery with neither capital nor name recognition clawing its way up relying solely on an obsession with sake quality—it can be said that the personality of the Hakkaisan brand was forged in the struggles of this reconstruction period. The philosophy of quality first, which the company would later uphold, was inherited as flesh and blood from the experiences of this era. Because it was a start from negative, the resolve to bet solely on sake quality without resorting to gimmicks was carved into the organization's genes.

Chapter 5: Kenjokai and Tetsuro Tanaka—Pouring the Philosophy of Ginjo into Ordinary Sake

To understand the sake brewing philosophy of Hakkaisan Brewery, one cannot avoid the existence of the study group known as "Kenjokai" and its leader, Tetsuro Tanaka.

In 1953, with Tetsuro Tanaka, who had retired from the National Tax Agency, as an instructor, the Kenjokai was formed by brewery owners in Niigata. Only about thirty years after the founding, the first brewery owner, Koichi Nagumo, was also listed as a member of this group. Tanaka's guidance was described as terrifyingly strict. It went beyond technical instruction for the Toji to include the formulation of annual plans for each brewery, as well as management policies and the mindset of a sake brewer, demanding an unforgivingly high standard from those who attended.

At the core of this guidance was the philosophy of Ginjo brewing. In an era when rice was scarce, he advocated for polishing rice, thoroughly drilling in the techniques of Ginjo, which are time-consuming and costly. Hakkaisan Brewery received this strict training head-on during its formative years. However, herein lies the uniqueness of Hakkaisan. The company chose the path of using the Ginjo techniques they had been drilled in not to create a special bottle of high-end sake, but to raise the quality of ordinary, everyday drinking sake.

Pouring the precise management techniques cultivated through Ginjo brewing into ordinary sake and Honjozo, which account for the majority of production—this became the consistent policy of Hakkaisan Brewery. In fact, so-called regular sake, from ordinary sake to special Honjozo, accounts for around 80 percent of the company's production. Contrary to the general pattern of gaining fame with high-end sake and earning volume with ordinary sake, Hakkaisan made it its mission to raise the quality of everyday drinking sake itself to a level approaching Ginjo. Aiming not for "expensive sake for special days" but for "sake of reliable quality that supports the daily dining table"—this shift in thinking became the driving force that pushed Hakkaisan to the pinnacle of local sake. Mastering Ginjo in the place of learning, and sticking to a policy centered on ordinary sake in the place of practice. This duality forms the foundation of Hakkaisan Brewery's technical philosophy.

Chapter 6: Combining Rice—The Techniques of Hakkaisan Brewery

Hakkaisan's sake brewing has a technical characteristic that stands out even among Niigata breweries. That is the point that they do not limit the rice used to a single variety, but use a combination of two or more types of rice for almost all their sake.

Niigata sake is often brewed with soft to ultra-soft water, inevitably resulting in a refreshing, light taste and a soft, smooth mouthfeel. While this is a virtue that goes well with Niigata cuisine, if one pursues only lightness, there is a danger that the original umami and fullness of sake will be lost. Hakkaisan Brewery's answer to this problem was the combination of rice.

The company uses Gohyakumangoku as the mainstay for sake-brewing rice, while using Miyamanishiki, Yamadanishiki, and Koshitanrei for high-end sake. For general rice, they use varieties such as Koshiibuki and Yukinosei, centered on Todoroki Wase. They skillfully combine these according to the quality design of the sake being brewed. For example, using general rice to bring out the umami of the rice within the lightness, and using Yamadanishiki to brew softness and aromatic notes.

Moreover, the way they combine them is extremely precise. While it is common practice in sake brewing to use different rice for Koji rice and Kake rice, Hakkaisan Brewery does not stop there. They say they change the rice used for each stage: making the yeast starter (shubo), and the first, second, and third additions of the three-stage mash (sandan-jikomi). Combining rice means that one must know and control all the various reactions that occur there. Why go that far? The belief that the depth of sake lies in harboring reliable umami and depth within lightness, rather than pursuing only lightness, supports this effort.

Even in a modernized, mechanized brewery, this technique requires the intervention of human hands. In the rice washing and soaking processes, the Toji calculates the necessary values based on the rice variety, the moisture content of that year, and the situation from the previous time it was brewed, and staff members stand by the machines to make fine adjustments at key points. In particular, Koji making is considered the most important department in the sake brewing process, and one-third of the labor required in the brewery per day is spent solely on this Koji making. Knowing the rice, knowing the water, knowing the Koji. Hakkaisan Brewery's dry and light sake is built upon the accumulation of such steady techniques.

This technical philosophy is also directly reflected in the product system of the sake. Hakkaisan Brewery's sake is structured with ordinary sake, which accounts for the majority of production, as the foundation, and layers of special Honjozo, Ginjo, Junmai Ginjo, and Daiginjo on top of that. In general breweries, the top-tier Daiginjo is often positioned as the culmination of technology, while ordinary sake is often treated as a low-priced product that merely supports volume. However, Hakkaisan Brewery's thinking is the opposite. They circulate the technology cultivated in the top-tier sake back to the ordinary sake that is drunk the most, raising the standard of everyday drinking sake. The Daiginjo is both a culmination and an experimental ground for improving ordinary sake. Limited edition sake, such as the freshly pressed raw sake "Echigo de Sorou" which is pressed only once a year in winter, is also positioned not as selling the scarcity itself, but as a message delivering the blessings of the season. The hierarchy of products is designed not as a ranking, but as a system in which technology circulates.

Regarding rice polishing, Hakkaisan Brewery's stance is also thorough. Polishing rice is a basic process for removing the outer layer of the rice, which is the cause of off-flavors, to obtain a pure sake quality. The philosophy of "polishing," which was drilled into them by Tetsuro Tanaka during the Kenjokai era, was inherited as equipment through investment in in-house rice polishing and the introduction of high-performance rice polishing machines. The resolve of the early days, which chose the luxury of polishing rice in an era when rice was scarce, is the source of today's pure sake quality.

Chapter 7: Expansion into Kanto and Abolition of Discounts—Decisions on Distribution Reform

Brewing excellent sake and delivering that sake to the world are separate challenges. During the era of the second-generation owner, Kazuo, Hakkaisan Brewery also made several bold decisions in the areas of distribution and sales.

The first task undertaken was the expansion of sales channels. Seeing that the era where Niigata's local sake could survive on local consumption alone was over, Kazuo relied on his connections to request business with wholesalers in Gunma and Kanagawa, aiming for expansion into the Kanto region. By putting more effort into sales activities than other breweries, the number of shops handling Hakkaisan Brewery's products gradually increased, and the name "Hakkaisan" became known to consumers. The conviction that having many people recognize the quality of this sake was the path to the brewery's long-term survival supported this proactive market development. The previous generation also believed that the accumulation of quality recognition was the path to corporate survival.

Another decision that symbolizes the philosophy of Hakkaisan Brewery is the abolition of discounting in 1979 (Showa 54). Turning their backs on price-cutting competition, they chose to maintain prices and instead divert those funds toward raw material costs and labor costs. Using good rice, paying fair wages to people, and ensuring quality through the accumulation of these efforts. This policy of not chasing short-term cheapness but competing on the value of the sake itself was a difficult choice by the industry standards of the time. However, this decision became the management foundation that protected Hakkaisan from the quagmire of price competition and allowed for the sustainable improvement of quality.

In terms of facilities, advanced investment continued from this period. In 1967, several local breweries jointly established a rice milling plant to achieve more rational rice milling. In 1983, they completed the burial of underground storage tanks ahead of the rest of the country, securing a stable, low-temperature aging environment. In 1985, they signed a special agency contract with a major beer company, further expanding their distribution network. In 1986, they established Hakkaisan Co., Ltd. as a sales company, setting up a system for manufacturing and sales. In 1989, they completed a bottling facility for 1.8-liter bottles and an underground cellar. An obsession with sake quality, supported by a trinity of reforms in management, distribution, and facilities, paved the way for Hakkaisan Brewery's leap forward.

Chapter 8: The Local Sake Boom and 'Tanrei Karakuchi' — The Glory and Shackles of the 'Phantom Sake'

In the 1980s, a local sake boom arrived in the Japanese sake market. While the market had previously been covered by mass-produced products from major manufacturers, the spotlight shone on unique sake brewed by small, local breweries, and consumer interest rose sharply. In particular, the "Tanrei Karakuchi" (light, dry, and crisp) flavor profile embodied by Niigata sake became the defining taste of this era.

In contrast to an era where rich, sweet sake was the mainstream, this was a dry sake that was clean, light, and had a crisp aftertaste. It did not interfere with the taste of food and was something you could drink forever without getting tired of it. This image of sake as a drink to accompany meals was polished by Niigata breweries using soft water, high-quality rice, and the skills of the Echigo Toji (master brewers). In Niigata, with the prefecture's brewing research institute at the core, technology was shared across breweries, and the common direction of Tanrei Karakuchi was refined by the entire region. Jiro Nagumo, the third generation of Hakkaisan Brewery, also honed his skills at the Niigata Prefectural Brewing Research Institute in his youth. Hakkaisan gained nationwide acclaim as a representative of this Tanrei Karakuchi style and became one of the entities driving the local sake boom.

During this era, Niigata sake was recognized not only for the power of individual brands but also as a collective brand called "Niigata Sake." Niigata breweries, which share the common environmental conditions of heavy snow, soft water, high-quality rice, and Echigo Toji, were loosely connected under the single style of Tanrei Karakuchi, forming a solid image in the minds of consumers that "Niigata sake is clean and easy to drink." Hakkaisan was one of the faces representing that collective image. The evaluation of the entire region pushed up individual breweries, and the quality of individual breweries enhanced the evaluation of the region—in this interaction, Hakkaisan established its position as synonymous with local sake.

However, popularity creates unexpected distortions. When demand exceeded supply, it was touted in the market as a "phantom sake" that was difficult to obtain, and it began to be traded at prices far exceeding the list price. It was a situation where scarcity itself was consumed as value. While many breweries welcomed this frenzy, Hakkaisan Brewery perceived it as dangerous.

The company put forward the concept of "supply responsibility." Deliver good sake to those who want it, at a fair price, and stably. This is the duty that a sake brewery must fulfill, and creating scarcity to make it an object of speculation is contrary to the essence of Hakkaisan as an everyday sake to accompany meals. Choosing long-term trust through the balance of quality and supply rather than short-term profit through premiumization—this stance remained an unwavering axis for Hakkaisan Brewery even after the heat of the boom cooled, and it became the foundation supporting the company's social credibility. Hakkaisan overcame the era of the local sake boom, where glory and shackles were two sides of the same coin, through the power of its philosophy. Choosing to remain an everyday sake without getting drunk on scarcity—the meaning of this choice became even clearer after the boom had passed.

Chapter 9: The Brewery and Facilities — The Crystallization of the 'Kowagura' Philosophy

A facility that symbolizes Hakkaisan Brewery's sake making is the "Kowagura." The name combines the "Ko" from the founder, Koichi, and the "Wa" from the second generation, Kazuo, embodying the will to inherit the philosophy of the brewery over two generations.

The construction of the Kowagura began with the No. 1 Brewery in 1955 (Showa 30), and was expanded in stages, with the No. 2 Brewery in 1964 and the No. 3 Brewery in 1975. In response to improvements in sake quality and increases in production volume, the company steadily developed its rice milling and storage facilities. To meet the growing demand for high-quality rice, they also started their own rice milling and introduced high-performance rice milling machines to achieve higher degrees of polishing. They built a system to support the ginjo philosophy of polishing rice from the facility level.

In 2004, the Second Kowagura was completed as a brewery for regular sake. This was an investment to further improve the quality of everyday sake, and it embodied the company's philosophy of making ordinary sake with the same care as ginjo sake in the form of the latest facilities. Although it is a spacious, clean, factory-like mechanized brewery, mechanization itself was not the goal. Whether it is machine-made or handmade, gathering what is necessary for delicious sake—that rationality is the core of Hakkaisan Brewery's facility philosophy. The fact that they have the equipment for year-round brewing but dare not use it, limiting sake making to between October and May to provide an off-season for the maintenance of machines and people, is also a testament to their insight for continuing to make good sake for a long time.

In recent years, Jiro Nagumo has spoken of a policy to strengthen small-group, elite sake making at the Kowagura, amidst the flow of fulfilling supply responsibilities through mass production. It is said that this brewery, where a mere few people work on the highest quality sake, has a culture of thoroughly "hammering in" skills that is difficult to obtain in a mass production system. As a place to pass on the spirit hammered into him by Tetsuro Tanaka at the Kenjokai to the next generation, the Kowagura remains the spiritual center of the company even today. A brewery that handles volume and a brewery that inherits quality and skill. Possessing both is the source of Hakkaisan Brewery's resilience.

Chapter 10: The Third Generation, Jiro Nagumo — Succession as a Challenger

In discussing the present of Hakkaisan Brewery, the presence of the third generation, Jiro Nagumo, is indispensable. Born in Niigata Prefecture in 1959, Jiro is the grandson of the founder, Koichi. After graduating from the Department of Brewing at Tokyo University of Agriculture Junior College in 1980 and studying as a trainee at the Niigata Prefectural Brewing Research Institute, he joined Hakkaisan Brewery in 1983 (Showa 58) as a sales employee.

Jiro himself recalls with a bit of self-deprecation that he did not intend to enter the sake industry from the beginning. However, after joining the company, the management system was steadily improved by his hand. It is noteworthy that he brought modern numerical discipline into sake management, which tended to rely on intuition and custom, with a high awareness of management accounting to set budgets and sales plans based on accounting figures. The method of establishing a system to grasp business performance in a timely manner and formulating product strategies based on data was unique in a traditional industry that tends to rely on intuition and experience. And in 1997 (Heisei 9), Jiro took over as Representative Director and led Hakkaisan Brewery as the third-generation owner.

The motto put forward by the third generation was clear: "Improving the quality of regular sake." The belief that improving the quality of the sake people drink every day leads to increasing the value of sake as a whole was a restatement of the philosophy inherited from the era of the 'Five Men' in modern management language. While calmly looking at the fact that it is difficult for the consumption of ordinary sake and honjozo to increase more than it is now due to the declining birthrate, aging population, and diversification of entertainment, Jiro emphasized the many things to be learned from tradition, and positioned his role as thoroughly pursuing quality-oriented sake making and helping consumers enjoy sake more richly in their daily lives.

In Jiro's management stance, an awareness of being a latecomer brewery flows consistently. Because it is a brewery with a short history, he always faces sake making with the feelings of a challenger. This coexistence of humility and a progressive spirit became the driving force that later led the company to diversified businesses beyond the framework of sake. In 2017, the company's management was selected for the Grand Prix of the "51st Good Company Awards," and its steady and innovative corporate management was widely recognized.

What this award symbolizes is the fact that Hakkaisan Brewery is not just a brewery that makes good sake, but a company with an excellent management body. The sake industry is often spoken of as a traditional industry that relies on the intuition of the Toji and the experience of craftsmen. But Jiro, without denying the value of that tradition, grafted modern management discipline onto it. He accurately grasped sales and profits as accounting figures, used them as a basis to build budgets, and planned product sales. By introducing the language of numbers into the world of craftsmen, Hakkaisan Brewery realized a rare management that bridges sensation and logic, tradition and modernity. The fact that bold business decisions such as diversification and overseas expansion were established not as reckless bets but as calculated challenges was due to this management foundation backed by numbers. The coexistence of a challenger's spirit and steady numerical management—this can be said to be the true essence of Jiro Nagumo as a third-generation manager.

Chapter 11: 'Rice, Koji, and Fermentation'—The Philosophy of Diversification

Entering the 21st century, Hakkaisan Brewery began to transform, far exceeding the boundaries of a sake brewery. However, this diversification was not a chaotic business expansion, but one driven by a clear philosophy. It is a corporate identity summarized in three words: 'Rice, Koji, and Fermentation.'

Jiro Nagumo speaks frankly about how his company cannot suddenly enter unrelated businesses, such as manufacturing automobiles. However, the techniques for handling rice, controlling koji, and managing fermentation cultivated through years of sake brewing can be applied to many products other than sake. Using these technical assets as a foundation, the company redefined itself as a 'company of rice, koji, and fermentation.' This was the fundamental idea behind its diversification.

Symbolic of this philosophy is how the company distances itself from its flagship sake product. Hakkaisan Brewery has adopted a policy of intentionally not placing the 'Hakkaisan' logo, written in brush calligraphy, on products other than sake. For example, looking at the packaging of their hit product, Amazake, it is not immediately obvious that it is a Hakkaisan Brewery product. This is an intentional choice. By limiting the 'Hakkaisan' brand to sake and allowing other products to develop as independent brands, the company expands its base without relying on its flagship name. This growth strategy, where each product stands on its own value, is the design philosophy supporting the company's diversification.

Jiro recognized early on the fragility of a business model dependent on a single pillar: sake. As the domestic sake market shrinks over the long term, the company expands into multiple businesses centered on the common asset of technology, ensuring its long-term survival. This stance of envisioning the company's permanence over a long time horizon resonates deeply with the fact that sake brewing itself is a process that requires a long time. Business diversification was not a departure from tradition, but a necessity for its survival.

What must not be overlooked here is that Hakkaisan Brewery's diversification does not mean a disregard for sake. On the contrary, it is the opposite. By making new businesses like Amazake, shochu, whiskey, and beer stable pillars of revenue, the sake department is freed from the pressure of short-term profitability. This allows resources to be allocated to challenges that are difficult to justify by efficiency alone, such as the small-batch, high-quality sake brewing at the Kowa-gura brewery. Diversification acts as a breakwater to protect the purity of the core sake business. Multiple fermentation businesses support each other, and as a whole, they form a single organism: a 'company of rice, koji, and fermentation.' The policy of nurturing each business as an independent brand was also wisdom to keep this organic structure healthy. Rather than hanging everything on one sign, each business stands independently while sharing the same roots. Hakkaisan Brewery's business structure is based on a design philosophy similar to that of a tree.

Chapter 12: Uonuma no Sato—A Center for Nostalgia and Peace

The complex facility 'Uonuma no Sato' demonstrates that Hakkaisan Brewery's diversification extends beyond mere product line expansion to the dissemination of regional culture.

Located at the foot of the sacred Mt. Hakkaisan, in a corner of Nagamori, Minamiuonuma, this facility is spread across a satoyama landscape with idyllic rural scenery. It was born from the desire to have visitors feel nostalgia and peace through the life and culture of the snowy country. In addition to production sites such as the Second Kowa-gura brewery, the Fukasawada Distillery for rice shochu and whiskey, the Sarukurayama Beer Brewery for craft beer, and a research building for studying 'rice, koji, and fermentation,' the facility is dotted with cafes, shops, confectionery shops, soba restaurants, bakeries, and employee cafeterias, all designed so that visitors can experience the food and culture of Uonuma.

Its development was gradual. In 2011, the confectionery and cafe 'Satoya' opened, strengthening its character as a hub for tourism and food. The fact that even the employee cafeteria is open to the public is a manifestation of the company's founding aspiration to be a company open to the region. Considering that the company began with the philosophy of 'bringing industry to the region,' Uonuma no Sato can be called the modern fruition of that philosophy.

One of the core facilities is the 'Hakkaisan Yukimuro' (Snow Storage). A yukimuro is a system that utilizes the wisdom of heavy snowfall regions, packing winter snow into a giant storage room to serve as a natural refrigerator. The Hakkaisan Yukimuro stores up to 1,000 tons of snow, and in its natural cold air, Junmai Daiginjo sake and other products are quietly aged at low temperatures. This attempt to utilize the nature of the snowy country itself as a brewing resource without relying on electricity is the most vivid embodiment of Hakkaisan Brewery's respect for its climate. The snow storage facility also includes a shop and a kitchenware store, making it a space where one can experience the culture of the snowy country.

Furthermore, the company launched the quarterly magazine 'To Uonuma' in 2003, continuously promoting the charm of Uonuma. In 2012, it opened 'Sennen Kojiya' in Azabujuban, Tokyo, as a base to deliver the rich food and culture of Uonuma to the metropolitan area, with a theme of rice, koji, and fermentation. That same year, it began selling salt koji using Hakkaisan's koji, starting an attempt to propose the food culture of koji itself as a product. Repositioning fermentation, the foundation of Japanese food, into modern life—the name Sennen Kojiya embodies the wish to pass on the richness brought by koji for a thousand years to come. It does not just sell sake; it conveys the value of the land and food culture that gave birth to that sake. The founding aspiration of 'bringing industry to the region' has thus, after a century, come to fruition in a new form: the dissemination of regional culture.

The experience of visiting Uonuma no Sato itself speaks to the philosophy of Hakkaisan Brewery. The spring of melting snow, the lush green summer, the autumn of ripening rice ears, and the winter covered in snow. The facilities scattered throughout the satoyama show different expressions amidst the colors of the four seasons, offering visitors an encounter with the true face of Uonuma. Local soba is served at the soba restaurant, sweets made with ingredients from the snowy country are offered at the confectionery shop, and bakeries and cafes add to the daily enjoyment. Uonuma no Sato is designed not only as a place to produce and sell sake, but also as a place to taste the life of the land that gave birth to the sake. The uniqueness of this facility lies in the fact that it does not chase the bustle of a tourist destination, but focuses on providing quiet values: nostalgia and peace. The technology and spirit cultivated in sake brewing permeate food, tourism, and culture, and visitors encounter the personality of the company known as Hakkaisan Brewery there.

Chapter 13: Amazake and Sparkling—Commercializing the Wisdom of the Snowy Country

The product that most significantly embodies Hakkaisan Brewery's 'Rice, Koji, and Fermentation' strategy is Amazake.

The company entered the Amazake market in 2009. Applying the koji control technology polished through sake brewing, 'Amazake Made Only with Koji' is a non-alcoholic beverage that brings out a natural sweetness using only the power of rice and koji without adding sugar, finished with a clean, elegant taste. This gained significant support and grew into the company's second pillar after sake. If the latest manufacturing plant, expanded in 2017, operates at full capacity, its production volume is expected to reach about half of the company's sake production volume, making Amazake a presence that significantly changes Hakkaisan Brewery's business structure. As mentioned above, the reason for intentionally not displaying the 'Hakkaisan' logo prominently on this product is due to the company's consistent philosophy of nurturing it as an independent brand. It is an example of accurately capturing the trend of rising health consciousness and the re-evaluation of Amazake with the technology of a sake brewery.

Challenges utilizing the wisdom of the snowy country continue. The idea of converting the apparent disadvantage of heavy snow into a brewing resource, like the Junmai Daiginjo aged in the snow storage, is the true essence of Hakkaisan Brewery. The company has also actively worked on the development of sparkling sake, which undergoes secondary fermentation in the bottle, opening up new drinking scenes for sake. Proposing a flow of drinking, starting from bubbles, moving to Junmai sake, and then to Honjozo, and offering consumers the way to enjoy sake itself, is also a characteristic of the company.

The brewery's character also appears in its winter-only products. The freshly pressed raw sake 'Echigo de Sorou,' pressed only during the peak of the sake brewing season, is a prime example. With two faces—the red label of Junmai Ginjo and the blue label of Honjozo—it delivers the satisfying drinkability unique to fresh, powerful raw sake and a crisp, refreshing aftertaste, like a seasonal greeting. At the root of this product development is not a stance of unilaterally affirming its own products, but of listening to the voices of consumers and exploring issues together. By offering many types of products to the world, the company proposes a life with alcohol, and by extension, a life with fermented foods. The 'Rice, Koji, and Fermentation' advocated by Hakkaisan Brewery is not just a slogan for manufacturing technology, but is being developed as a proposal for people's dining tables and lives.

Chapter 14: From Shochu to Whiskey—The Challenge of the Long Time of Distilled Spirits

For a brewery of fermented liquor to step into distilled spirits is not an easy decision, either technically or managerially. However, Hakkaisan Brewery has steadily moved forward in this area as well, eventually gaining global recognition.

The challenge of distilled spirits began in 2005 with the production of rice shochu at the Fukasawada Distillery in Uonuma no Sato. Products were created by leveraging the resources cultivated through sake brewing, such as authentic kasutori shochu made from fresh sake lees—a byproduct of sake production—as well as rice shochu and plum wine made using rice shochu and undiluted sake. The shochu named 'Yoroshiku Senman Arubeshi' is a representative brand of this endeavor.

From the process of aging this shochu in wooden barrels, the next challenge sprouted. In 2016, Hakkaisan Brewery began producing whisky at the Fukasawada Distillery. As a challenge unique to a sake brewery, it is a rice grain whisky with rice as the main ingredient. The brewing water used is the same famous 'Raiden-sama no Shimizu' water used for sake, and sake yeast is utilized for fermentation. While following traditional whisky-making methods, this attempt incorporated unique techniques exclusive to a sake brewery, aiming for a rare spirit with few parallels globally.

In 2019, the company took an even bigger step. It established a subsidiary, Niseko Distillery Co., Ltd., and began construction of a full-scale whisky distillery in Niseko Town, Hokkaido. The reasons for choosing Niseko were based on a convergence of several conditions. Surrounded by Mount Yotei and Niseko Annupuri, the area is blessed with high-quality soft water unique to a heavy snowfall region, and the Shiribetsu River, famous as a clear stream, flows through it. The basin climate, which remains cool even in summer, is suitable for whisky aging, and the area's character as a world-class snow resort visited by many foreign guests serves as a stage to promote products to the world. It is said that the background for selecting this location also included empathy for Niseko Town's stance of valuing coexistence with nature, such as limiting building heights to protect the natural landscape. Finding in this land a climate that shares commonalities with Uonuma—heavy snow and high-quality soft water—also bolstered the decision.

The Niseko Distillery began operations in 2021 and started producing craft gin alongside malt whisky. While equipped with stills from Forsyth's of Scotland and committed to full-scale whisky production, gin was the first product released to the world while waiting for the whisky, which requires time to age, to be completed. Named 'ohoro,' which means 'to continue' in the Ainu language, this gin was finished with a clear yet robust flavor using a carefully selected blend of botanicals, including bog rosemary and Japanese peppermint produced in Hokkaido. This gin, imbued with the wish that the spirit born in Niseko would be loved for a long time, eventually earned high praise at global competitions.

In 2024, 'ohoro GIN' won the world's top award in the Classic Gin category at a global gin competition and also received the highest award at another international spirits competition, growing into a representative presence for Japanese craft gin. Then, in 2025, Hakkaisan Brewery finally released its first whisky product to the world. It is a single grain rice whisky, rare even globally, made primarily from rice at the Fukasawada Distillery and aged for eight years in American and French oak barrels. This bottle, released in limited quantities, marked the culmination of 20 years of distilled spirit production. In the future, the company envisions the completion of a one-of-a-kind Japanese whisky that blends the rice whisky made in Uonuma with the malt whisky nurtured in Niseko.

Underlying the challenge of distilled spirits is the resolve to accept long periods of time. From preparation to commercialization, whisky requires at least several years, and ten to twenty years for true completion. It is precisely because Hakkaisan Brewery has stable businesses like sake and amazake that it can afford to wait for that long duration. Preparing resources with an eye five or ten years ahead and envisioning a company that never ends—the distilled spirits business is the most symbolic embodiment of Jiro Nagumo's long-term management philosophy.

This attitude toward time resonates deeply with the essence of Hakkaisan Brewery as a company. Sake is also an endeavor that follows time: growing rice, cultivating koji, and nurturing moromi. Surrendering to the rhythm of nature, not rushing, yet not being idle, and waiting for things to mature. Distilled spirits push this stance to the limit. The completion of whisky can sometimes require a span of time equivalent to a person's entire professional career. The true value of the raw spirit prepared at this very moment will be judged in the world ten or twenty years from now. Even so, the act of entrusting barrels of certain quality to the future is premised on the conviction that the company will continue to exist for a long time and on a sense of responsibility to the next generation. Having a scale of time that differs from the market logic of competing for short-term profits—this is the resolve Hakkaisan Brewery has poured into the words 'a company that never ends,' and it is an extension of the stance toward craftsmanship that this brewery has consistently chosen since its founding.

Chapter 15: Beer, the Third Fermentation, and the World

Alongside sake, shochu, whisky, gin, and amazake, another pillar that colors Hakkaisan Brewery's fermentation business is beer.

The company's beer business originated from local beer production started within the Izumi Village in September 1998. Initially popular under the 'Izumi Beer' brand, Hakkaisan Brewery significantly revamped it in July 2018. It relocated the brewery to Uonuma no Sato, established the new Sarukura-yama Beer Brewery, and changed the brand name to 'RYDEEN BEER.' This facility, where visitors can observe the brewery through glass, is one of the embodiments of the fusion of tourism and manufacturing in Uonuma no Sato. The craft beer, which utilizes the clear water of the snowy country, enhances the appeal of local food and tourism along with the attached beer bar.

Engaging in the world of beer, a fermentation process different from sake, was a natural expansion of the business domain under the common denominator of fermentation for a company that upholds 'Rice, Koji, and Fermentation.' The company's business now extends into every direction of fermentation and brewing: brewed sake, distilled spirits like shochu and whisky, beer as a different type of brewed alcohol, and gin, as well as amazake using koji. However, these are not scattered randomly; they are organically connected as branches extending from a single trunk of philosophy: rice, koji, and fermentation.

The company's gaze has already crossed national borders. Overseas expansion began when a Japanese supermarket in the United States reached out, but now, the number of people interested in sake is steadily increasing in Europe, including France, and in the United States. Hakkaisan Brewery, which foresaw the potential of overseas markets early on, has also focused on disseminating information abroad, such as by welcoming an American sommelier as a brand ambassador. The vision is grand, including exporting the 'Rice, Koji, and Fermentation' technology cultivated through years of sake brewing and even considering local sake production. The fact that the whisky and gin made in Niseko, a world-class ski resort, are gaining recognition at global competitions shows that Hakkaisan Brewery is a brewing company capable of competing in the global market, transcending the contraction of the domestic market. As the domestic sake market shrinks, broadcasting from a land where information flows to the world—that strategy is inseparably linked to the vision of long-term corporate survival.

Chapter 16: The Centennial and Beyond

In 2022, Hakkaisan Brewery celebrated its 100th anniversary. A century has passed since the first president, Koichi Nagumo, started a small sake brewery in the former Jonai district, looking up at the sacred Mount Hakkai. After rebuilding from a deficit of less than 300 koku, the company has become a representative local sake brewery of Niigata and has grown into a comprehensive enterprise centered on fermentation and brewing.

On the occasion of the centennial, the third-generation president reaffirmed the belief in sake quality that has remained unchanged since the founding. By pursuing high-quality, crisp, and balanced sake and improving the quality of regular sake for everyday drinking, the value of sake itself is enhanced. The foundation built by the 'Five Fellows' with a shared ambition is passed down across generations. Continuing to brew clear sake unique to this land, nurtured by the rich nature of Uonuma and the culture of the snowy country—that determination was also a reaffirmation of the company's mission to connect the inherited traditions, wisdom, and solid brewing technology to the future. Learning much from failures and continuing trial and error without stopping thought or progress. The stance of remaining a challenger remains at the core of the company even after a hundred years.

This century has by no means been an easy era for the sake industry itself. Domestic consumption of sake has followed a long-term decline since its peak in the mid-1970s, forcing many breweries to close. Amidst structural headwinds such as the diversification of entertainment, the younger generation's drift away from alcohol, and population decline, it is no longer possible to hope for the consumption of ordinary sake and honjozo to return to previous levels. The fact that Jiro Nagumo has faced this reality without sentimentality and calmly stated that 'further growth is difficult' forms the premise of Hakkaisan Brewery's management decisions. In a shrinking market, how can one continue to brew good sake and survive as a company? The company's answer to this question was a three-pronged strategy: thorough high-quality improvement of regular sake, diversification of business centered on 'Rice, Koji, and Fermentation,' and expansion into the global market. The milestone of the centennial is not viewed as a break to reminisce about the past, but as a point to reaffirm the strategy for surviving the next hundred years.

Regarding the development of successors, Jiro also speaks with optimism and conviction. Thinking back to his own experience as a young man inheriting a brewery burdened with heavy debt, he says there is no need for the next generation inheriting such a foundation to be unnecessarily tense. While inheriting the culture of honing skills at the elite Hirokazu Brewery, the company balances the responsibility of supply through mass production with the challenge of achieving the highest quality. In terms of both organization and human resources, Hakkaisan Brewery is steadily making preparations for the next hundred years.

Final Chapter: Path Dependence and Gift—What a Century Shows

When re-examining the path of Hakkaisan from a longer perspective, two analytical viewpoints are effective. One is the perspective of path dependence, and the other is the perspective of gift.

Path dependence refers to a phenomenon where choices made at a certain point in time orient the range of subsequent choices, making it difficult to deviate from the path once formed. The history of Hakkaisan Brewery can be read precisely as a chain of this path dependence. The philosophy of ginjo, 'polishing,' which was drilled into them at the Kenjokai during the founding period, prepared for subsequent investments in in-house rice polishing and created an accumulation of equipment. The choice to abolish discounting in 1979 fixed a management model that kept a distance from price competition and strengthened the single path of quality-first. The decision to refuse to become a 'phantom sake' during the local sake boom and instead choose the responsibility of supply required a production system and distribution design premised on stable supply, which further distanced the company from a premium-only route. Each choice bound the next, eventually crystallizing into a consistent philosophy from which there was no turning back. Hakkaisan's 'unwavering nature' was both a belief and a structural consequence brought about by the path of choices accumulated over a hundred years.

Another perspective is that of the gift. At the root of Hakkaisan Brewery's business lies an orientation toward a gift-based relationship that cannot be fully reduced to equivalent exchange in the market. The founding motivation of 'bringing industry to the region' was, in a sense, an advance gift to a land deep in snow and lacking in industry. Opening the employee cafeteria to the public, developing Uonuma no Sato as a hub for regional culture, and conveying the charm of the land through a quarterly magazine are behaviors that go far beyond the price of sake as a product, seeking to return value to the region itself. The ideal of sake that accompanies meals, enhances conversation, and never tires the palate is also rooted in the idea of viewing sake not as a commodity, but as a medium that supports relationships at the dining table. What Hakkaisan has embodied is a stance of trying to build continuous relationships between seller and buyer, and between company and region, that transcend one-off transactions.

If path dependence unravels the mystery of Hakkaisan's consistency, the concept of the gift illuminates what that consistency has been directed toward. Receiving the blessings of an unchangeable climate, brewing sake worthy of them, and returning value to the region and the dining table. The hundred years of the Hakkaisan brewery are situated within this cycle of receiving, responding, and giving back.

Conclusion: What Was Hakkaisan?

Looking back over the history of Hakkaisan, a paradox emerges. Why was this brewery, which was a latecomer, had a short history, and refused to use scarcity as a selling point, able to stand at the pinnacle of local sake?

The answer lies in the fact that Hakkaisan Brewery has consistently stood on the side of the 'everyday.' It is not an expensive bottle for a special day, but a reliable sake that accompanies the daily dining table and never tires the palate. It is not a 'phantom' sake that fuels scarcity, but a sake that can be delivered stably to those who seek it at a fair price. It is a brewery that does not boast of the brilliance of Ginjo, but quietly pours that technology into the quality of its ordinary sake. What Hakkaisan has embodied is the modest, yet most difficult, ideal of maximizing the quality of daily life.

And this ideal has expanded beyond the framework of refined sake. Amazake, shochu, whiskey, gin, and beer. The many branches that have grown from the trunk of rice, koji, and fermentation technology are all being developed to enrich people's daily lives. The hub of Uonuma no Sato offers not just sake, but the culture of the snowy country itself as a daily joy. The founding ambition of 'bringing industry to the region' has been inherited as a single stream of contribution to the region and to life, while changing its form.

Water, rice, snow, and people. Taking the blessings of an unchangeable climate as its greatest asset, the brewery continues to produce sincere sake worthy of them. Without losing the awareness of a challenger, and with the resolve to undertake a long period of time, it envisions a lasting enterprise. Just as the mountain's faith began with prayers to the water god, the activities of Hakkaisan Brewery also start with respect for nature. The hundred years of Hakkaisan is a record of how a single bottle of sake became a philosophy, and how that philosophy shaped a corporate culture. Like the clear water springing at the foot of the Echigo Sanzan mountains, its work flows quietly, yet ceaselessly, into the next hundred years.
