K.K. Rokuwa (㈱六和, translated as Rokuwa Co., Ltd.) was a Japanese distributor, already active in 1949.[1] Its headquarters were in Tokyo, Muromachi (室町), and it had a plant in Tachikawa (立川).[2] In the 1950s, it also had addresses in Osaka, Fukuoka and Sapporo.[3]

The company was perhaps called Rokuwa Shōji (六和商事) at the beginning of the 1950s.[4]

The company was the owner of the brand Minori (みのり), and it sold the Minori film, Minori photographic products and Minoriflex 6×6 TLR.[5] In the 1950s, it also used the Rocca brand for some cameras.
