In 1937, old battleship ASAHI was converted to a repair ship of limited capabilities. ASAHI saw but little repair duty early in the war. She was torpedoed and sunk in May 1942.

In 1940, AKASHI, the only specifically designed repair ship constructed by the IJN, was commissioned. AKASHI performed battle damage repairs to many IJN warships at Truk while converted merchants YAMABIKO HAKKAI, URAKAMI, SHOEI and YAMASHIMO MARUs conducted similar repair work at major IJN bases such as Kwajalein, Truk, Rabaul and Palau.
