Background

• In 1925, the Swedish American Line constructed the passenger liner MS Kungsholm. The Nippon Yusen Kabushiki Kaisha (日本郵船,, NYK Line) was concerned about the MS Kungsholms construction.
• 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 Terukuni Maru class were named the Terukuni Maru (照國丸) and Yasukuni Maru (靖國丸).
