TheOsumi-class tank landing ship were a class of transport ships operated by theMaritime Self-Defense Force. It was recommissioned with the donation of threeLST-542-classtank landing ship from theUS Navy. Initially, it was categorized as aamphibious landing ship, but the ship type was changed on 1 April 1971.^[1]

TheMaritime Self-Defense Force's transport and landing craft unit consists of sixgeneral-purpose landing craft (LCUs) (built in Japan by extraterritorial procurement) and mobile landing craft (built in Japan) provided by theUS Navy based on the MSA Agreement in 1955 (Showa 30). It all started with the establishment of a fleet of 29 ships. However, all of these were small, had limited transport and landing capabilities, and lacked seakeeping. From this, based on the MSA agreement, threeLST-542-class tank landing ships, which had beenmothballed in theUnited States, will be provided.

TheLST-542 class was the last model of theLST-1-classtank landing ship, and the displacement is increased by adding one layer of bridge and adding machine guns based on the early model, and it is also the latter model In comparison, the amount of cargo loaded has been reduced to 1,900 tons due to the strengthening of water production capacity. In addition,Ōsumi-class had three davits on each side that could carry landing craft such asmobile landing craft (LCM) andvehicle personnel landing craft (LCVP), butJDSShiretoko has a bridge structure. There is only one on each side.
