TOKYO (AFP) - An American military helicopter burst into flames after landing in an empty field in Okinawa on Wednesday (Oct 11), the Japanese Defence Minister said, with no injuries reported.
The US military told Japanese authorities that their CH-53 transport helicopter "landed" before the fire erupted in the early evening just outside a training ground on the island, said Mr Itsunori Onodera.
National broadcaster NHK showed dramatic footage of firefighters battling orange flames after dark and plumes of black smoke billowing into the sky.
"When the US Marine Corp CH-53 helicopter landed, a fire started. We have received information that all crew members were safe," Mr Onodera told reporters.
Japanese authorities asked the US military to provide a full report and take steps to prevent a similar accident.
"Accidents by the US Marine Corps are continuing. We want to communicate to the US side that we demand safe operations," Mr Onodera said.
According to eyewitnesses cited by NHK, the accident occurred shortly after 5.30pm.
Officials from the US Marines based in Okinawa could not immediately comment.
In December, five crewmembers aboard a US Marine MV-22 Osprey were injured after what the Pentagon described as a "mishap" resulted in the plane landing in shallow water off Okinawa.
At that time, Prime Minister Shinzo Abe said it was "very regrettable" that a "serious accident" had occurred and stressed that the plane's safety record was a "prerequisite" to the aircraft's deployment in Japan.
The deployment of Ospreys in Japan has prompted protests by Okinawa residents after a series of accidents in other countries involving the hybrid aircraft.
In August, US Marines were forced to mount a major search-and-rescue mission after an MV-22 Osprey crashed of the east coast of Australia.
They rescued 23 out of the 26 personnel and eventually called off the hunt for the three remaining crew.
More than half the approximately 47,000 American troops in Japan under a decades-long security alliance are stationed on Okinawa, the site of a major World War II battle that was followed by a 27-year US occupation of the island.
