Ars Seiki Kōgyō K.K. (アルス精機工業㈱, meaning Ars Precision Industries) was a Japanese company, whose name appeared in mid 1952 as the maker of the Tomy camera with Z-shaped light path, designed by Sakurai Minoru (桜井実).[1] The production of the Tomy was soon taken over by Zuihō Kōgaku Seiki.[2] It seems that the Zuihō company was already active before that date, and was not a renaming of Ars Seiki (see Zuihō).

It is not known if the company was related to the Ars company, publisher of the photo magazine Ars Camera, which once offered the Arsen camera and distributed a few photo accessories.
