Nishiki Secret Air Base Museum (山の中の海軍の町 にしき ひみつ基地ミュージアム) 山の中の海軍の町 にしき ひみつ基地ミュージアム
A naval air base active for 21 months: 1,500 m runway, over 6,000 trainees, tunnels with a guide.
The Hitoyoshi naval air base was built by the navy from November 1943: a concrete runway 1,500 metres by 50 and an area with headquarters and quarters. On 1 February 1944 the Hitoyoshi naval air corps was formed, at first to train mechanics, and from May also trainee pilots: more than 6,000, in a valley with neither sea nor lake. After two American raids and as the war worsened, the base moved on to training kamikaze pilots and then to home defence, and in the spring of 1945 workshops, depots, barracks and an operations room were dug underground. The first raid, on 18 March 1945 with carrier aircraft, killed 9 servicemen and 4 civilians; the last, on 14 May, killed no one. The corps was disbanded on 10 July 1945, after only one year and nine months of activity. In 2015 a group of volunteers discovered that what looked like an air-raid shelter was a large navy installation; the following year they handed the materials over to the municipality of Nishiki, which opened the museum in August 2018. The official name is 錦町立人吉海軍航空基地資料館.
