From chemical raw material manufacturer to pharmaceutical manufacturer

The Otsuka Group began with the establishment of Otsuka Seiyaku Kogyo-bu (Otsuka Pharmaceutical) in Naruto City, Tokushima Prefecture, in 1921 by the founder Busaburo Otsuka (1891-1970). At that time, it was a chemical raw material manufacturer that produced magnesium carbonate (listed in the Japanese Pharmacopoeia) from salt field residues.

In 1946, we started manufacturing intravenous infusion solutions, entered the pharmaceutical field, and in 1951, we launched IV solutions in glass vials. Subsequently, as the demand for IV solutions expanded, we developed a variety of IV solutions, particularly in 1968, we launched Japan’s first plastic container for IV solutions and established a position in the IV industry.
