Rokkor was a brand name used for all Chiyoda Kōgaku Seikō and later Minolta lenses between 1940 and 1980, including a few which were marketed and sold by other companies like Leica. The name was derived from the name of Rokkō (六甲山), a 932 metres (3,058 ft) high mountain, which could be seen from the company's glass-making and optics factory at Mukogawa near Osaka, Japan.
