🇯🇵Helicopter incidents in Japan

This database records 20 helicopter incidents in Japan, the earliest in 2009 and the most recent in 2026. 1 has been recorded so far in 2026. The worst single year was 2020, with 4 incidents.

37 deaths across 8 fatal accidents, which is 40% of all incidents recorded here. Every other accident in Japan was survived by everyone on board. The deadliest was on 2018-08-10 at Nakanojo, which killed 9.

The most frequently recorded type is the Leonardo AW139 with 4 incidents, followed by the Robinson R22 with 2. That reflects how many of each type fly in Japan rather than how safe they are.

Where a cause has been established, the most common is controlled flight into terrain, in 3 accidents, then mechanical failure in 2. Many records carry no established cause, either because the investigation is open or because none was published.
