Miyagawa Seisakusho (宮川製作所) was a Japanese company from as early as 1935. It made the Picny 3×4 camera and the Boltax and Bolty cameras using Bolta film. It is called Miyagawa Seiundō (宮川星雲堂) in the April 1943 government inquiry on Japanese camera production; its address at the time was Tōkyō-to Nakano-ku Kami-chō 131 (東京都中野区上町131).[1]
The company survived the war. It perhaps made the Silver, a continuation of the Boltax with auto-stop advance. In 1948, it released the Picny B, a redesigned camera taking Bolta film. The Picny 35 and Royal 35 were derivatives taking perforated 35mm film. Miyagawa perhaps also made other cameras called Royal before disappearing.
