The Ōsumi class (おおすみ型輸送艦), is a Japanese tank landing ship. The class is also known as the Oosumi class. While the Japan Maritime Self-Defense Force (JMSDF) describes the Ōsumi class as tank landing ships (LSTs), 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).
As of 2024 there are three Ōsumi vessels active with the Japanese Maritime Self-Defence Force.
