Kanto

Kanto Optical Corp. (関東光学株式会社, Kantō Kōgaku Kabushiki Kaisha) was a Japanese company that made the Amiflex 6×6 TLR around 1953-4. "Kantō" loosely means East Japan, or the area of Tokyo as opposed to Kyoto and Osaka.

It is unknown if it is related with the Ami 4.5×6 folder advertised during World War II.
