Hikawa Maru
In 1927-28, the NYK Line placed an order for eight ocean liners to reinforce the Japan–Seattle route (3 × "Hikawa Maru" class), Japan–San Francisco route (3 × "Asama Maru" class), and Japan–London route (2 × "Terukuni Maru" class). The "Hikawa Maru" class were named the "Hikawa Maru", "Hiye Maru" (later "Hei Maru") and "Heian Maru".
