The {{nihongo|Kawasaki-type oiler|川崎型油槽船,|Kawasaki-gata Yusōsen}} was a type of oiler from Japan, serving during the 1930s and World War II. They do not have an official class name.Iino Lines called Tōa Maru class, Kawasaki Line called Tatekawa Maru class, Nittō Mining called Nichiei Maru class, and more... Therefore, this article uses common class names. And, this type has some variants. This article handles them collectively.

Background

File:Fujisan Maru.jpg

  • The London Naval Treaty forced shrinkage of a budget to the Imperial Japanese Navy (IJN). And it meant the cooling of the Japanese shipbuilding industry worlds. The Great Depression accelerated it more. The IJN wanted to update their Notoro-class oilers and Ondo-class oilers, because these oilers were not able to chase the aircraft carrier.
  • In 1929, the IJN decided their combat ship (battleship, aircraft carrier, cruiser, destroyer, submarine and torpedo boat) fuel only to heavy crude oil. And, the IJN was paid a grant to newly build large/high-speed tankers.
  • In 1931, two marine transportation companies built the tankers which the IJN wanted. One was the 9,900 tons/17.5 knot Teiyō Maru, the other the 9,500 tons/18.8 knots Fujisan Maru.
  • The IJN was satisfied by Fujisan Maru. The IJN recommended building of the improved Fujisan Maru class tanker.

Construction

  • In 1932, the {{nihongo|Iino Kaiun Kaisha|飯野海運,|Iino Lines}} ordered two tankers Tōa Maru and Kyokutō Maru to the Kawasaki Shipbuilding Corporation. In total 17 tankers were built with the same basic drawings, until 1943.
  • All sisters participated to World War II. However, they were not able to survive at all.

  • This is the first production model of the Kawasaki-type tankers. Their success gave courage to other steamship companies.

  • The second production model. They were built according to the same Tōa Maru class drawings. However, their details were different by the steamship company which they placed an order with (example: Nippon Maru removed one dry cargo hold). Narrow sense of the Kawasaki-type tanker was until the Kyūei Maru. Kyūei Maru was equipped for surplus stocks of the Argentina Maru machinery.
