Built as a high speed luxury car ferry in 1972 for Nihon Kosoku Ferry K. K. by Kawasaki Heavy Industries Co., Ltd. She was one of the original Sun Flower fleet of two vessels, Sun Flower and Sun Flower 2, to which slightly larger version of the original series, Sun Flower 5 and Sun Flower 8 were added later. The difference between the original series and Sun Flower 5 and 8 is that the bridge of Sun Flower 5 and Sun Flower 8 were located one deck higher than that of Sun Flower and Sun Flower 2. Though Sun Flower 11 is often included in the original Sun Flower series but her design is completely different from the first four vessels.
Both Sun Flower and Sun Flower 2 were first put on the service between Nagoya - Kochi - Kagoshima. In 1976, with the financial assistance of MOL lines, both vessels were transferred to Taiyo Ferry Co., Ltd. and put in the service between Osaka - Karita in 1977. In 1979, they went through a major renovation, such as conversion of an outdoor swimming pool into an indoor heated water pool, addition of a restaurant theater with an observatory room etc. In 1984, both vessels were exchanged with the Ferry Kogane Maru and Ferry Nishiki Maru of Kansai Kisen K. K., and joined the Kansai Kisen fleet. Though Kansai Kisen later sold them to Kurushima Dockyard, Kansai Kisen chartered both ships back and put them on their Osaka - Kobe - Beppu service until they retired from Japanese water in 1998.
After retiring from Japanese water, she wa sold to a South Korean operator in 2000, and a North Korean operator in 2005 however, it is not sure if she was put in a passenger service.
