The Kamikawa Maru-class cargo ship (神川丸型貨物船, Kamikawa Maru-gata Kamotsusen) was a type of cargo ship of Japan, serving during the 1930s and World War II. Four of the five ships of the class were converted to seaplane tenders during the war.

History

In 1930, the Ōsaka Mercantile Steamship Co.Ltd. (O.S.K. Lines) put into service the Kinai Maru-class cargo ship[1] on the Japan-New York route. Competing Japanese steamship companies produced and placed their own cargo ships on the North America route.

In 1936, the Kawasaki Line built four Kamikawa Maru-class ships. They had much higher cruising speeds and capacity than their competitors. However, they were commandeered in sequence and did not survive to the end of the war.
