History of Otsuka
Otsuka Group started in 1921. Busaburo Otsuka established a chemical compound factory in Naruto, Tokushima Prefecture, now Otsuka Pharmaceutical Factory Inc. In 1946, this small-scale manufacturer of chemical raw materials began producing and selling intravenous solution. In 1950, the organic chemical division split from Otsuka Pharmaceutical Factory to from Otsuka Chemical and Medical Products, Inc., now called Otsuka Chemical. This was followed by the establishment of Taiho Pharmaceutical in 1963 and Otsuka Pharmaceutical in 1964. These new entries were steps in the evolution of a manufacturer specializing in R & D.
In 1973, the international expansion of the Otsuka Group started with the establishment of Thai Otsuka Pharmaceutical Co., Ltd., aggressively driven by Otsuka Pharmaceutical. The Otsuka group has grown into a group consisting more than 150 companies worldwide.
