History

Naokichi Kaneko, chief clerk of the integrated trading company named "Suzuki Shoten," and two chemical engineers, Seita Kumura and Itsuzo Hata, cooperated to establish Japan's first rayon production technology, and in 1918, they launched Teikoku Jinzo-Kenshi Kaisha, Ltd.
In the 1960s, following the golden age of Japan's rayon industry in the 1930s and the post-war recovery period, the polyester fiber product named Tetoron® gave the company a driving force to boost its business performance. Subsequently, in the high economic growth period, the company planned to increase its net sales to two trillion yen, and to this end strived for globalization, launched a business in the film field, and worked on the diversification of its business.
In the 1990s, after the collapse of the so-called "bubble economy" in Japan, Teijin set its corporate philosophy to survive in the world of the 21st century. It shifted to a holding company system, implemented structural reforms, and reformed its portfolio, including expanding the core business through M&As.
In the progress of globalization, the focus of its fiber business shifted to high-performance fibers, while in the chemicals business the company pushed ahead with the construction of resin manufacturing facilities outside Japan and forming alliances in the film field. It also released an important new drug in the pharmaceutical business and established a pioneer position in the home healthcare field, and also developed new businesses in the IT field.
Teijin has thus been continuing to take on the challenge of entering new fields, overcoming difficulties, and persisting in its evolution. We will continue to undertake reforms and embrace challenges to become a company that supports the society of the future.
