This gallery contains pictures of the JASDF Piasecki H-21 found at the Tokorozawa Aviation Museum based in Saitama prefecture near Tokyo, Japan. For a little history, the JASDF operated 10 H-21B helicopters as rescue machines, while the JGSDF operated 2 Model 44A “Hou-Ou” helicopters for testing.

The aircraft can be entered from both sides and even the cockpit is open for entry, providing a great view of what the inside looks like. Near the aircraft are also some various engines, including ones used with this aircraft.
