The was a class of two support ships of the Imperial Japanese Navy (IJN), serving during World War II.
In 1939, the IJN planned two support ship classes to help their aircraft carriers. One was the 8,000-ton, the other one the 4,500 ton Sunosaki class. The Sunosaki was planned to support for two medium-sized carriers (and) in the battlefield. The thought is the same as USS Sacramento.
The Sunosaki class was unable to support Japan's carrier task force, because their commissions were delayed. They sailed between the Japanese mainland and Southeast Asia, and were lost before participating in a naval battle.
