The Ōsumi class LST (おおすみ型輸送艦), is a Japanese amphibious transport dock. While the JMSDF describes the Ōsumi class as tank landing ships, they lack the bow doors and beaching capability traditionally associated with LSTs. Functionally, their well deck makes the Ōsumi class more like a dock landing ship (LSD) or amphibious transport dock (LPD).
Globalsecurity.org noted in its report on the Ōsumi class that "the program originated in a proposal for a small carrier for defensive and mine countermeasures (MCM) purposes, but this was deemed politically unacceptable, and the project was reworked as an amphibious ship".[dubious ]
