🏭 The Truth Behind 'No-Price-Hike Management' Learned from Saizeriya: 5 Industry Survival Strategies Decoded from a Field Perspective

✅ Conclusion first: 'Not raising prices' is not a heartwarming story; it is a battle of process design.

Milan-style Doria for 300 yen. It has remained almost unchanged for five years.

Behind the scenes, Saizeriya has doubled its sales in five years and turned an operating loss into 15.5 billion yen in profit. This isn't some pretty story about 'doing it for the customers.'It is manufacturing-style management that fixes prices and squeezes out profit through process design.And this structure isn't just about Saizeriya.

Gig work, disability welfare, AI construction machinery, and public space design—five industries that look completely different are actually facing the same problem.

It is the problem of **'how to handle the cost of human beings.'**

📌 What is so amazing about 'no-price-hike management' in the first place?

Let's look at the price hike situation in the restaurant industry.

While others are raising prices by 20-30%, Saizeriya haskept prices almost flat. Hearing just this, one might conclude, 'Their corporate efforts are amazing!'

But wait a minute.

🔍 The truth about 'not raising prices' seen through the numbers

Did you see it?

The domestic operating profit margin is only 2.9%. 65% of their profit comes from their Asian operations, centered on China.

In other words, what supports 'not raising prices' is not just domestic effort.It is a dual structure where profits earned overseas compensate for the thin margins in Japan.that is.

🏭 Seen through the eyes of manufacturing, it was the 'Toyota Production System of Food'

From here, I will cut into this with the field perspective of 25 years in manufacturing.

Watching Saizeriya's management, I have a sense of déjà vu. This is not the management of a restaurant company.It is factory production management itself.

In 2008, the president at the time took on the role of head of work analysis himself, bringing video cameras into stores to start motion analysis. Cutting cleaning time in half. Halving kitchen space to expand seating.

This is IE (Industrial Engineering) itself. It is only rare for a restaurant company to do this; it is a standard method in manufacturing sites.

💡 'Not raising prices' is not a decision. It is the result of process design.

In manufacturing, saying 'costs went up, so let's raise prices' is a B-grade idea. A-grade is 'design a process that generates profit even if costs rise.' Saizeriya is managed with exactly that A-grade mindset.

🔗 The magic word 'idle time' connects 5 industries

This is where we get to the main point. Saizeriya's 'no price hike' management is actually part of a much larger structural change.

'Idle time'—in other words, the time when people, goods, and spaces are sitting unused. This question is exploding simultaneously across completely different industries.

While they may seem unrelated, they all stem from the same urge to **'get idle resources working.'**

And what is interesting is that each is hitting a different wall.

⚡ The reality of 'monetizing gaps' by industry

1️⃣ Gap-time part-time job market: The price of rapid growth

The gap-time part-time job market has tripled in two years.

'One in three stores cannot function without gap-time workers'—this is the reality of the food service industry.

However, the distortions of rapid growth are appearing. About 47% of workers have experienced trouble. 'I was called by my app name and they didn't even bother to learn my real name,' 'I was blocked for writing an honest review.'

And in September 2025, the platforms will roll out a major rule change. Labor contracts will be finalized at the moment of matching, and companies will be required to pay leave allowances for cancellations made for their own convenience.

What does this mean?

Gap-time labor, which was supposed to be 'cheap and usable only when needed,' will effectively turn into a fixed cost.

'Even if the worker is low-rated, I have no choice but to hire them once the match is made'—I can hear the screams from the front lines.

2️⃣ Disability welfare: The collapse of the 'gap in the system' business

After-school day services have increased eightfold since 2012 (from about 2,900 to over 22,700 locations). The budget for disability welfare has also quadrupled in 19 years (from about 500 billion yen to over 2.2 trillion yen).

However, it is not just 'high-quality support' that has increased. 'Daycare-style' facilities that just let children watch TV or focus on DVDs and games have become rampant.

The government's response is clear. Lowering compensation for short-term support and a 15% deduction for not publishing support programs—using penalties to force 'low-quality operators' out of the market.

What happens if a 15% reduction is applied to an industry with a 5% profit margin?The answer is one thing: immediate insolvency.

Approximately 40% of facilities are already in the red. In just a few months of 2024, over 300 Type A employment support offices closed, leaving more than 5,000 people with disabilities without a place to go.

3️⃣ AI Construction Machinery: The Ultimate 'Systematization' That Eliminates Humans

Komatsu introduced the world's first commercial unmanned dump truck in 2008. Currently, over 750 units are in operation, with a cumulative transport volume exceeding 10 billion tons. Over the past 20 years, Caterpillar has invested approximately 4.5 trillion yen in R&D and is promoting full autonomy through a comprehensive partnership with NVIDIA.

24 hours a day, 365 days a year, they don't get tired. They don't complain. They don't take unauthorized leave.The more you use them, the more data is accumulated, and performance improves.

This is being weighed against the 'risk of hiring humans'.

4️⃣ Calm Down Spaces: The 'Protected Areas' of an Optimized Society

Over 80% of people with sensory sensitivities have experienced giving up on going out. Quiet spaces (calm down spaces) have begun to spread in airports and train stations. They are also installed at Yumeshima Station on the Osaka Metro.

At first glance, this is a welfare issue, but from a field perspective, it has aparadoxical meaning.

As a result of society as a whole pursuing efficiency too much, the need to intentionally recreate 'inefficient margins' has emerged.

📊 Lining Up 5 Industries by 'Degree of Systematization'

This is the most important point when viewed through the eyes of the manufacturing industry.

│ 障害福祉       │ 転嫁先なし     │ ×       │ ×（4割赤字→崩壊中） │
└──────────────┴──────────────┴──────────┴─────────────────────┘

The sustainability of cost absorption is directly proportional to the 'degree of systematization'.

Komatsu's unmanned dump trucks are the 'pinnacle of systems.' Once invested, marginal costs continue to fall, and ROI increases over time. Disability welfare is the exact opposite; the room for systematization is structurally small, and there is no pricing power. The only way to absorb losses is through human endurance.

Saizeriya is in between. They have pushed systematization to the limit using IE methods and DX, but they are near their limit in the domestic market alone.

⚠️ Is 'Not Raising Prices' Really Justice? — 3 Risks

Risk 1: The Shock of a 1,500 Yen Minimum Wage

The government's goal is a minimum wage of 1,500 yen around 2029–2031. This represents a **+34% upward pressure on labor costs** from the current 1,121 yen.

If Saizeriya's labor cost ratio of 24% rises by 3 points to 27%, their domestic operating profit margin of 2.9% will becomealmost zero.

Risk 2: Dependence on the Chinese Business

Asian operating profit accounts for 65% of the company's total. If geopolitical risks were to materialize, this profit structure would collapse from its foundation. Relying on only one pillar to support 'not raising prices' is a high-risk management strategy.

Risk 3: The Fixation of 'Cheap Japan'

As long as companies that do not raise prices continue to exist, the virtuous cycle of 'service prices leading to wages' will not be completed. Even if wage increases of over 5% are achieved in the spring labor offensive, if they are not reflected in service industry prices, the improvement in real wages will be delayed.

Behind a 300-yen Milanese-style Doria, there are food service employees working for a monthly income of 259,000 yen (60,000 yen lower than the all-industry average).

The most probable is the neutral scenario (55%).In an environment where the food service CPI continues to rise by 4% annually, it is structurally difficult to maintain 'no price hikes' for more than 5 years. However, there is a wildcard.

However, there is a wildcard.What if fully automated cooking robots powered by AI are put into practical use within 5 years? It is possible that labor costs could be pushed down to 15% or less, leading to the emergence of a new form of low-price model.

💎 Conclusion: Are You the 'Rule Maker' or the 'One Being Optimized'?

The essence that has emerged across five industries is this.

**'Inability to raise prices' is merely a superficial phenomenon. The essence is that the 'degree of systematization' determines the life or death of an industry.**

└──────────────────────────────────────────────────────────┘

From 25 years of experience in the manufacturing industry, I can state one thing with certainty.

The more standardization progresses, the more 'exceptions' remain at the end. And it is humans who absorb those exceptions.

Even if labor is saved through DX, customer complaints, sudden staff shortages, and unexpected troubles—these do not disappear. The burden that bounces back to those areas is the ignition point for turnover, quality degradation, and service collapse.

When I was involved in a DX project in the past, the ones who resisted most fiercely were not the frontline workers, but **'middle managers who maintained their own value through ambiguous authority and buffers (slack time).'** What platformers and the government are doing right now is the same structure. They are presenting costs in the name of revised terms and penalties, forcing a choice between 'following the system or exiting.'

🎯 What Should You Do Starting Tomorrow?

👔 If You Are a Business Person

Examine your company's 'cost absorption mechanism.' Is it running on systems, or is it running on the endurance of the frontline?Are you measuring labor productivity? Saizeriya aims for 6,000 yen. How much is it at your workplace?

And, let's take inventory of the 'exception handling' on the front lines. Who is stuck, when, and on what? The burden that doesn't show up in KPIs (inquiries, cancellations, handling staff shortages) is what is eating away at the organization from the inside.

📈 If You Are an Investor

Add 'process design capability' to your evaluation criteria, not just 'pricing power.' Look at domestic and overseas operating profit margins separately. Track the trend of labor cost ratios. Qualitatively evaluate how much investment in DX and automation is contributing to productivity.

Don't forget the fact that companies that did raise prices are also seeing record profits across the board (Skylark OP +107%, Yoshinoya OP +132%).'Not raising prices' is not the only correct answer.

🏠 For the average consumer

While enjoying the benefits of a 300-yen Milanese Doria, let's understand the structure behind it. Low prices are partly supported by someone else's low wages or unstable employment. Could the unconditional belief that 'price hikes = evil' be creating a structure that, in the long run, suppresses your own wage growth?
