Asahi Kasei

Asahi Kasei Corporation is an international chemical and material sciences company headquartered in Tokyo, Japan. It is among the top three chemical companies in Japan, joining Sumitomo and Mitsubishi at the pinnacle of the tier. Its main products are chemicals, fibers, pharmaceuticals, construction materials, and medial and electronic devices. A little more than 29,000 employees work at 54 Asahi Kasei facilities around the world.


Asahi Kasei was founded in 1922 under the name Asahi Fabric Company. In 1931, it began producing nitric and ammonia acids, giving birth to Asahi Kasei Chemical Company. The name was changed to Asahi Chemical Industry Co., Ltd in 1946. In 1949, Asahi began a joint venture in petrochemicals production with DOW Chemical—Asahi-Dow. Beginning in the 1960s, Asahi Kasei began to accelerate its diversification into a number of sectors, including semiconductors, electronics, pharmaceuticals, housing construction, glass fabrics, engineered resins and liquors. Asahi was the first to use hydroelectric power to produce ammonia, thereby setting the foundation for its chemical fibers and synthetic chemistry business. Asahi_Kasei_Nobeoka_Branch_2010
