Kunisaki is a Ōsumi class LST of the Japan Maritime Self-Defense Force (JMSDF). The ship was built by Hitachi, Maizuru and commissioned into service on 26 February 2003.

The Ōsumi class LST (おおすみ型輸送艦), is a Japanese amphibious transport dock. The class is also known as the Oosumi class. 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)
