In the late 1920s the Japanese shipping company Nippon Yūsen (NYK) began a major shipbuilding program, aimed at expanding its international passenger service. Of eight passenger liners built, three were of the "Hikawa Maru" class, designed mainly for service on NYK's Yokohama-Seattle route. The three ships were the "Hikawa Maru", "Hiye Maru", and "Heian Maru".
