Gifu-Kakamigahara Air and Space Museum

This museum has several ww2 related exhibits among which are the largest a Mitsubishi A6M1 Replica, a Kawasaki Ki-61 Hien fighter, a Lockheed Neptune P-2 (designed during Ww2 and first flight in 1945) and an Aichi E13A waterplane. Kakamigahara itself was known as the stage for many first flights of prototypes of Japanese designed aircraft like the Mitsubishi A6M Zero.
