Doi (株式会社ドイ Kabushiki Kaisha Doi) was a large Japanese retailer and distributor, best known outside Japan as the company that revived the Plaubel Makina 67 camera in the late 1970s and early 1980s. Its roots go back to Doi Shōten (土居商店), also referred to as Doi Shōkai (土居商会). This was a Japanese retailer, distributor, or both, that started in 1949. (Doi here is a surname, shōten means "retailer", and shōkai means "trading company".) In the early fifties it was based in Osaka.
