Hachiyō Kōgaku Kōgyō K.K. (八陽光学工業㈱) or Hachiyo Optical Co. was a Japanese company known for making Alpenflex and Stereo Alpen cameras.

The company had its origin in a fortified factory set up during the war by Nippon Kōgaku in Yamagata Prefecture (in the north of Japan's main island).[1] In an advertisement for the Alpenflex I (or IS), Tanaka Shōkai makes explicit Hachiyo's origin as the Shiojiri (塩尻) factory of Nippon Kōgaku, and also uses Hachiyo's manufacture of microscopes as a sales point.[2]

The company went out of business in 1955.[3]
