At least two camera-related Japanese companies were called Katsuma:
- In 1932, a company called Katsuma Kōgaku Kikai Seisakusho is cited as one of the two founders of Tōkyō Kōgaku (see this page).
- In the 1950s, Katsuma Kōgaku Kōgyō K.K. was the new name of Fuji Kōgaku (see this page). It was also a binocular maker, sometimes using the English name Katsuma Optical Company.
