Yaimamaru

Yaimamaru is a roll-on/roll-off passenger ship (ROPAX) launched in 1997 at Mitsubishi Heavy Industries Shipbuilding Shimonoseki Shipyard for the Blue Highway Line (currently MOL Sunflower). She sailed under the Japanese flag as the Sunflower Kuroshio until 2001. The South Korean shipping company PanStar Cruise acquired her in 2002, and she began operating on the Busan–Osaka route as the PanStar Dream until a newer ship took her place. Since August 2025, she's been sailing under the Panamanian flag and is set to serve the Ishigaki–Keelung route by the Japanese shipping company YaimaLine.

== Design and construction == Sunflower Kuroshio, built to replace Sunflower Tosa, was constructed under yard number 1034 in Shimonoseki and launched on 21 March 1997. Named after the Kuroshio Current, which flows through the Pacific Ocean along her intended service route. The design concept of the vessel is a “leisurely cruise in yukata” (), featuring interior décor inspired by traditional Japanese inns. Passengers can enjoy wearing yukata while relaxing in the ship's communal areas.
