Two US Ospreys reportedly make emergency landings in Japan

Two US military Osprey aircraft made separate emergency landings at airports on Japanese islands on 14 August, with no injuries or damage reported, local media said.

One of the two MV-22 Ospreys landed at Amami Airport in southwestern Kagoshima prefecture on 14 August afternoon, according to the Kyodo and Jiji news agencies.

The tilt-rotor aircraft left the Japanese airport two hours later, interrupting some commercial flights, public broadcaster NHK said.

The other Osprey made an emergency landing further south at the US Kadena Air Base in Okinawa on 10 August afternoon, Kyodo said, quoting government sources.

There were no reports of injuries or damage following the two incidents.

Immediate confirmation of the news reports was not available.

The Osprey, a hybrid helicopter-turboprop with a chequered safety record, has two engines positioned on fixed wingtips that allow it to land and take off vertically. It can travel much faster than a helicopter.

Several accidents involving US military aircraft in Japan have stoked tensions between Washington and Tokyo and led to protests against the deployment of Ospreys by residents living near US bases.

The incidents have included emergency landings by US military helicopters, a piece of a helicopter falling on the grounds of a Japanese school, and the deadly crash in 2017 of an MV-22 Osprey which forced a massive rescue operation.

US Defense Secretary James Mattis apologised to his Japanese counterpart over the mishaps in January 2018.
