Construction
The Ondo class was initially planned in 1920 as the six of the Kamoi-class oilers under the Eight-eight fleet final plan. However, of the Kamoi-class oilers, only the Kamoi was completed, due to the conclusion and signing of the Washington Naval Treaty. The other five vessels were then re-planned to the Modified Notoro class.
Out of the five ships, one became the icebreaker Ōtomari, while the other become the food supply ship Mamiya. Therefore, only three ships were built as Modified Notoro-class (Ondo-class) oilers.
Service in peacetime
They devoted themselves to importing crude oil from North America and Southeast Asia. The crude oil which the Ondo class and the Notoro class carried to Japan was 388 sorties; 3,000,000 tons, until 1941.
Service in Pacific War
They were not able to accompany heo fleet, because they were low speed. They were engaged in supply duties at naval bases.
