Ogawa Kazumasa (1860 - 1929) was a Japanese photographer, printer and publisher who was a pioneer in photomechanical printing and photography.
In 1889, he set up Japan's first collotype business, the Ogawa Shashin Seihan jo. In the same year, Ogawa worked as an editor for Shashin Shinpō (Photography journal), the only photographic journal available at the time.
Ogawa was a founding member of the Japan Photographic Society, which gathered photography amateurs from all around Japan. In 1891, he was charged with taking 100 pictures of Tokyo's most attractive geisha, to commemorate the opening of the Ryōunkaku.
