OKAYA CITY Okaya was known around the world by "Silk Okaya" from the Meiji era through the early years of the Showa era. After the Pacific War (1941-45), it has developed as a city of precision industry mainly producing watches and cameras. Okaya today is making its confident advances as a producing center of "smart devices" using its cutting-edge technologies of optics, super-precision processing and machinery. In the city, there are a large number of manufacturers boasting their unique technologies. In cooperation with the Nagano Precision Industry Research Institute and the Techno Plaza Okaya, these enterprises are offering frontier products, technologies and information to the world.
