One of the foundations of Toyobo, Osaka Boseki was born

Osaka Boseki was established on May 3rd, 1882, and started operation as Japan's first large-scale spinning mill in 1883.
When nighttime production started, the lighting inside the factory was switched from oil lamps to electric lighting. Lighting was supplied from an Edison-style DC generator from September 1886, and it was the first of its kind to be used in a private factory. At that time, the only other electric lights were in the Imperial Palace in Tokyo, and in the Military Academy.
