is a squadron of the Japan Maritime Self-Defense Force based at Marine Corps Air Station Iwakuni in Yamaguchi Prefecture, Japan. It operates MCH-101 aircraft.
As of 2016 there were seven MCH-101 aircraft in service with the squadron and plans for a total of 11. There were also discussions for the purchase for over a dozen additional aircraft.
Two retired MH-53E helicopters of the squadron were sold to the US in 2015 for their components. The US was running short of parts for its own fleet of the aging aircraft.
