History

Establishment and Early Years (1918-1945)

Teikoku Jinzo-Kenshi Kaisha, Ltd., the predecessor to Teijin, was established on June 17, 1918, in Yonezawa, Yamagata Prefecture, as Japan's first commercial producer of rayon, an artificial silk fiber derived from cellulose. The company originated from a rayon manufacturing plant initially set up in 1915 under Azuma Leather Co., Ltd., which was separated and reorganized with an initial capital of ¥1 million to focus on synthetic textile production. Founded by Naokichi Kaneko of the Suzuki Shoten trading firm, along with chemical engineers Seita Kumura and Itsuzo Hata, the venture imported rayon technology from Europe following extensive development efforts that began as early as 1908 with precursor companies like Nihon Celluloid Jinzo Kenshi Kabushiki Kaisha. By 1917, the team had refined the process to produce 100 pounds of high-quality rayon yarn daily, aligning with early international standards.^[12][3] In the 1920s, Teikoku Jinzo-Kenshi advanced domestic rayon manufacturing through key innovations in production techniques, enabling scalable operations amid Japan's growing textile industry. The company launched its first major facility, the Iwakuni Factory in Yamaguchi Prefecture, in 1927, which initiated large-scale production of rayon filament yarn and marked a shift from experimental to commercial viability. This period saw the development of proprietary processes to reduce reliance on imported expertise, supporting Japan's industrialization drive for self-sufficient synthetic fibers as an alternative to natural silk.^[12][3] Pre-war expansion accelerated in the 1930s, with Teikoku Jinzo-Kenshi growing into a leader in synthetic fibers through strategic investments and capacity enhancements. The establishment of the Mihara Factory in Hiroshima Prefecture in 1934 doubled production infrastructure, allowing output to surge to 60 million pounds of rayon yarn by 1937 and positioning the company as Japan's largest rayon producer, ahead of rivals like Toyo Rayon Ltd. Government policies promoting heavy industry facilitated mergers and consolidations after October 1941, further integrating operations to boost efficiency in filament and staple fiber production.^[12] World War II profoundly disrupted operations, imposing resource shortages and redirecting efforts toward military needs under strict government directives. Raw material scarcities, including wood pulp and chemicals, hampered production, while factories were compelled to manufacture military textiles, parachutes, and even airplane fuel components. Equipment was systematically dismantled and repurposed for weaponry, leading to asset freezes and severe capacity reductions; rayon staple production ceased at Mihara in March 1945 and at Iwakuni in April 1945, effectively halting civilian output by war's end. The postwar occupation forces imposed additional controls, setting the stage for reconstruction.^[12]

Postwar Growth and Diversification (1946-1990)

Following World War II, Teijin, then known as Teikoku Jinzo Kenshi Kaisha, faced severe disruptions from wartime production halts and facility damage, but rapidly resumed operations in 1947 with approval from the General Headquarters (GHQ) to expand rayon capacity to 150,000 tons annually.^[12] By rebuilding key plants like Iwakuni and Mihara, the company restored rayon yarn production from 2.02 million pounds in 1946 to 42.5 million pounds by 1955, while staple fiber output grew from 1.3 million to 37.75 million pounds over the same period.^[12] This recovery was bolstered by the Korean War boom, which drove sales to ¥8.1 billion and profits to ¥3.7 billion in the early 1950s, enabling further infrastructure investments such as the Komatsu plant in 1949 and the Nagoya plant in 1951.^[12] In May 1949, the company listed on the Tokyo, Osaka, Nagoya, Fukuoka, and Sapporo stock exchanges, marking its re-entry into global markets through increased exports of synthetic fibers amid Japan's postwar economic stabilization.^[12][3] The 1950s and 1960s saw explosive growth during Japan's economic miracle, propelled by the introduction of synthetic fibers that diversified Teijin's portfolio beyond rayon. In 1958, leveraging technology licensed from Imperial Chemical Industries (ICI), Teijin began commercial production of polyester fiber, branded as Tetoron®, which quickly became the company's cornerstone product and accounted for 82% of profits by 1960.^[12] This innovation drove revenue expansion, with Tetoron enabling robust exports and supporting global market penetration, including early ventures like a joint production facility in Sri Lanka in 1961.^[3][12] Diversification accelerated into adjacent areas, including polyester films for packaging and industrial uses, as well as resins; by 1963, Teijin entered upstream production of raw materials like terephthalic acid, followed by dimethyl terephthalate in 1964 and paraxylene in 1968, reducing dependency on imports and enhancing cost efficiency.^[12] The company also formed subsidiaries such as Teijin Acrylic Ltd. in 1959 to specialize in new fiber types, solidifying its position as a leader in high-performance synthetics.^[12] In the 1970s and 1980s, Teijin navigated economic turbulence while pursuing broader diversification into pharmaceuticals and information technology precursors. The 1973 and 1979 oil crises severely impacted its petrochemical-dependent operations, leading to deteriorated performance by 1977, with the company reducing its workforce from 10,346 to 7,446 employees between 1977 and 1978 and withdrawing from unprofitable rayon yarn production in 1971.^[12] In response, Teijin shifted strategically toward high-value materials, emphasizing advanced fibers and resins to mitigate volatility in raw material costs.^[12] Entering pharmaceuticals, it established Teijin Pharmaceutical Co., Ltd. in 1978, which received approvals for its first drugs, including Venilon® and Laxoberon®, launching sales in 1980 to address unmet needs in intravenous nutrition and laxatives.^[13][3] Early IT-related efforts emerged through electronics materials like polyester films for circuit boards, while international joint ventures expanded, such as a 1969 polyester technology partnership in South Korea and alliances in Asia to bolster overseas production.^[14] By 1982, polyester film operations turned highly profitable, contributing to pre-tax profits of ¥37.6 billion by 1990.^[12] In 1962, reflecting its evolution into a diversified synthetic fiber powerhouse, the company renamed itself Teijin Limited.^[12]
