In 2012, former Defense Minister Satoshi Morimoto ordered an investigation of the costs of V-22 operations. The V-22's capabilities exceeded current Japan Self-Defense Forces helicopters in terms of range, speed and payload. On 21 November 2014, the Japanese Ministry of Defense officially decided to procure 17 V-22s and the first V-22 for Japan was delivered in August 2017. In September 2018, the Japanese Ministry of Defense decided to delay the deployment of the first five MV-22B aircraft it had received amid opposition and ongoing negotiations in the Saga prefecture, where the aircraft are to be based. On 8 May 2020, the first two of the five aircraft were delivered to the JGSDF at Kisarazu Air Field after failing to reach an agreement with Saga prefecture residents. It is planned to eventually station some of the aircraft on board the Izumo-class helicopter destroyers.
