Toyokawa Naval Arsenal

The land was acquired in the towns of Toyokawa and Uchikubo and village of Yawata in eastern Aichi Prefecture by July 1938, and construction began on October 1, 1938.

In addition to aircraft weapons, the Toyokawa Navy Arsenal also produced optical equipment such as rangefinders and binoculars.

Despite its obvious military significance, the Toyokawa Navy Arsenal was not bombed until the very last stages of World War II.
