Stable supply system of 3 plants with high production capacity

Towa has total of 14 billion tablets with 3 plants combined, Osaka, Okayama, and Yamagata Plant.
We are now constructing a system to boost our manufacturing capacity to 17.5 billion tablets per year to cope with the increasing demand. For the purpose of the stable supply of Towa’s product, the products of oral formulations are separated in 3 portions, and each portion is allocated to 1 of the plants, respectively. On the other hand, injectable are manufactured only at a building with quake-absorbing structure in Yamagata Plant. These measures and policies minimize the disaster risk. The 3 plants in compliance with PIC/S GMP achieve high quality and stable supply of products and to support the future with trust.
Osaka plant serves as a tablet technology plant responsible for introducing new products with general formulations, while Okayama plant serves as a mass production technology plant for handling various products including capsules, powders, and granules. Yamagata plant serves as a comprehensive technology plant handling solid formulations, sterile formulations, and their high potent active pharmaceuticals.
