[Manufacturing] Fukuoka Prefecture Manufacturing Analysis (Part 2): The Strength, Development Trajectory, and Future Prospects of Kyushu's Strategic Economic Hub

This is a continuation from the previous part.

1. Historical Background: The Trajectory of Fukuoka Prefecture's Manufacturing Development

The background to how Fukuoka Prefecture's manufacturing industry built its solid foundation today lies in a combination of geopolitical advantages, abundant natural resources, and the accumulation of foresight and effort that has adapted to the changing times. I will detail this trajectory chronologically.

2. Dawn Period: Development of the Chikuho Coalfield and the Stirrings of Modern Industry (Late Edo Period to Mid-Meiji Period)

The origin of industrialization in Fukuoka Prefecture, particularly in the Chikuho region, lies in coal resources. While coal mining had already been confirmed in some areas by the end of the Edo period, after the Meiji Restoration, as Japan's modernization became an urgent task, the importance of coal as an energy source increased dramatically.

• Full-scale development of the Chikuho Coalfield: Under the Meiji government's policy of promoting new industries, the Chikuho Coalfield rapidly developed into the largest coalfield in the country. High-quality and abundant coal was indispensable as factory power, for steam locomotives, and as ship fuel, literally supporting Japan's Industrial Revolution as "black diamonds." At its peak, it accounted for about half of Japan's coal production, contributing significantly to energy supply both domestically and internationally.

• Progress in infrastructure development: For efficient transport of coal, port facilities such as Wakamatsu Port (part of the current Kitakyushu Port) were developed and expanded, and a railway network connecting the coal mines to the ports (such as the Chikuho Kogyo Railway, later the Japanese National Railways) was laid one after another. This improved coal loading capacity and established the foundation for industrialization.

• Accumulation of labor force: Coal mine development required a large labor force, and many people from both inside and outside the country moved to the Chikuho region. This became the foundation for the labor force necessary for later industrialization.

3. Leap Period: Establishment of the Government-run Yawata Steel Works and the Progress of Heavy Industrialization (Late Meiji Period to Taisho Period)

With the Chikuho Coalfield as a backdrop, a major project that would determine Japan's heavy industrialization was realized in Fukuoka Prefecture.

• Establishment of the Government-run Yawata Steel Works (1901): After the Sino-Japanese War, the domestic production and stable supply of steel were the nation's most important issues. The government, based on a comprehensive judgment of the following:

  • 1) Availability of coal from the Chikuho Coalfield,

  • 2) Presence of a port (Dokai Bay) advantageous for importing iron ore,

  • 3) National defense perspective,

  • 4) Ease of securing a labor force,

  • established the Government-run Yawata Steel Works, Japan's first full-scale integrated steel mill, in Yawata Village (now Yawata-Higashi Ward, Kitakyushu City).

• The Path to Technology Introduction and Domestic Production: Initially, the industry relied on technology imported from overseas, such as from Germany, but while overcoming the technical difficulties of the early operational period, the establishment of independent technology by Japanese engineers gradually progressed. This contributed significantly to the improvement of Japan's technological capabilities.

• Formation of a Heavy Industry Cluster: The operation of the Yawata Steel Works spurred the development of the steel-based machinery industry, shipbuilding industry (which also influenced nearby Nagasaki and Shimonoseki), and metal processing industry. Furthermore, chemical industries (sulfuric acid, dyes, fertilizers, etc.) utilizing byproducts from coke ovens, as well as the cement and glass industries, also accumulated derivatively, and the region centered on Kitakyushu City transformed into one of Japan's leading heavy and chemical industrial zones.

• Impact of World War I: World War I (1914–1918) served as an opportunity for Japan to increase its steel self-sufficiency rate and expand production capacity, as steel imports from Europe were cut off. The Yawata Steel Works also established a system for increased production, supporting Japan's military industry and contributing to the improvement of its international status after the war.

4. Development and Trials: Wartime Regime and Post-War Reconstruction (Early to Mid-Showa Period)

• Strengthening Under the Wartime Regime and Transformation into a Military Supply Hub: Following the Manchurian Incident, as Japan leaned toward a wartime regime, the Kitakyushu industrial zone became increasingly important as a production hub for weapons, ships, aircraft parts, and more. While production capacity was significantly expanded, it also faced problems such as harsh working conditions and resource depletion.

• World War II and War Damage: Toward the end of the Pacific War, because it was a military supply hub, it became a target for strategic bombing by the U.S. military, and factory groups, including the Yawata Steel Works, suffered significant damage.

• Post-War Reconstruction and the Korean War Special Procurement: After the war, while being affected by the dissolution of the zaibatsu and industrial regulations by GHQ, the reconstruction of the steel industry, a key industry, progressed through methods such as the priority production system. In particular, the "Korean War special procurement" following the outbreak of the Korean War in 1950 caused a rapid increase in demand for steel, cement, machinery, etc., and boosted the rapid reconstruction and regrowth of the Kitakyushu industrial zone.

• Contribution During the Period of High Economic Growth: As Japan entered the period of high economic growth (late 1950s to early 1970s), the Kitakyushu industrial zone played an important role in supporting Japan's economic growth. With vigorous capital investment, infrastructure development, and the spread of durable consumer goods, material industries such as steel continued to operate at full capacity.

5. Turning Point: The Energy Revolution and the Challenge of New Industries (Late Showa to Heisei Period, and to the Present)

The end of high economic growth and changes in the domestic and international economic environment also forced a major transformation in Fukuoka Prefecture's manufacturing industry.

• The Energy Revolution and the End of the Chikuho Coal Field: Entering the 1960s, the "Energy Revolution" progressed, in which the main energy source shifted from coal to inexpensive and easy-to-handle oil. Domestic coal mines were forced to close one after another, and the Chikuho coal field also brought its history to an end. As a result, the coal-producing region suffered a serious economic blow, and unemployment problems arose.

• Structural Changes in the Steel Industry and International Competition: Due to the oil shocks and the rise of emerging countries, the steel industry faced intensified international competition and changes in the demand structure. Rationalization of facilities and a shift to high-value-added products were required.

• Strategic Attraction and Accumulation of the Automotive Industry: Aiming to revitalize coal-producing regions and foster new leading industries, Fukuoka Prefecture actively promoted the attraction of the automotive industry. The start of operations at the Nissan Motor Kyushu plant (currently Nissan Motor Kyushu Co., Ltd., Kanda-machi, Miyako-gun) in 1975 and the start of operations at Toyota Motor Kyushu, Inc. (Miyawaka City) in 1992 are symbolic events. With the entry of these large-scale factories, many parts manufacturers and related companies accumulated, and northern Kyushu transformed into a major automotive production hub forming the core of "Car Island Kyushu." This industrial shift contributed significantly to new job creation and the revitalization of the regional economy.

• Diversification of Technology and Expansion into New Fields: The advanced metal processing technology, automation technology, and quality control technology cultivated in the steel and machinery industries became the foundation for expansion into new fields, not only in the automotive industry but also in industrial robots (such as Yaskawa Electric), semiconductor manufacturing equipment parts, and environment-related technologies.

In this way, Fukuoka Prefecture's manufacturing industry started from the initial resource advantage of coal, and has overcome many rough waves—heavy industrialization centered on national steel projects, wartime and reconstruction, and the energy revolution and major shifts in industrial structure—to form a new industrial cluster centered on the automotive industry. It can be said that this historical experience, along with the technological capabilities, human resources, and entrepreneurial spirit cultivated there, form the resilient foundation of the current Fukuoka Prefecture manufacturing industry and support its future development potential.
