The Notoro class oiler (能登呂型給油艦 Notoro-gata kyūyukan?) was a class of seven oilers of the Imperial Japanese Navy (IJN), serving during the 1920s and World War II. They were also called the Erimo class oiler (襟裳型給油艦 Erimo-gata kyūyukan?), after the Notoro and the Shiretoko were converted to other ship types.

Construction[edit]

They were built under pre-Eight-eight fleet plans, the Eight-four fleet plan and the Eight-six fleet plan. All ships of the class were named after capes in Japan (e.g. Irō is a cape at the southern tip of Izu Peninsula).

Pre-war service[edit]

The class devoted themselves to importing crude oil from North America and Southeast Asia. The Notoro and the Ondo class made 388 voyages carrying a total of 3,000,000 tons of oil up to 1941.

Service in the Pacific War[edit]

They were not able to accompany the fleet, because of their low speed. Instead they were engaged in a supply duties at naval bases.
