K.K. Rokuwa (㈱六和, translated as Rokuwa Co., Ltd.) was a Japanese distributor, already active in 1949. Its headquarters were in Tokyo, Muromachi (室町), and it had a plant in Tachikawa (立川). In the 1950s, it also had addresses in Osaka, Fukuoka and Sapporo.
The company was perhaps called Rokuwa Shōji (六和商事) at the beginning of the 1950s.
