JS Izumo (DDH-183) is a helicopter carrier which, as of 2022, is being converted into a light aircraft carrier. Officially classified as a multi-purpose operation destroyer, she is the lead ship in the Izumo class of the Japan Maritime Self-Defense Force (JMSDF). She is the second warship to be named for Izumo Province, with the previous ship being the armored cruiser Izumo (1898).

The ruling Liberal Democratic Party announced in May 2018 that it favours converting Izumo to operate fixed-wing aircraft.^[4] The conversion was confirmed in December 2018 when Japan announced the change of its defense guidelines. Upon the completion of the process, Izumo will be the first Japanese naval vessel to operate fixed-wing aircraft since World War II.^[5]
