Production Factory
Delivering High-quality Products
Quickly and Reliably
For a pharmaceutical manufacturer, it is essential to have a system
in place that enables the quick and reliable supply of high-quality products.
At Sato Pharmaceutical, production is the responsibility of
our central Hachioji Factory and the Kazusa Factory, which features the latest equipment.
Both the Hachioji Factory and the Kazusa Factory have world-class production systems
that meet global Good Manufacturing Practices (GMP).
