Origin of the name “Chugai”
When Chugai was established as “Chugai Shinyaku Shokai” (March 10, 1925), the founder Juzo Ueno named the company “Chugai” to mean “domestic and overseas,” indicating his aspiration to eventually market Japanese drugs overseas.

In August of 1979, we changed the design of the corporate logo to strengthens its appeal and established its meaning as a corporate symbol by placing the word CHUGAI within the logo.
