TOKYO — A fatal crash of a U.S. Marine Corps aircraft in Hawaii has renewed safety concerns in Japan, where more of the Ospreys will be deployed.

Gov. Takeshi Onaga on the southern island of Okinawa said Monday that flights of the hybrid aircraft should be suspended until the cause of the crash is found.

"From the (Okinawan) residents' point of view, Osprey deployment is not acceptable to begin with," Onaga told a televised news conference. "The significance of this crash is extremely big. We seek adequate investigation into the cause and explanation, and of course eventually demand withdrawal of Ospreys."

Onaga also said he planned to demand the U.S. military to suspend all Osprey flights on the island until the authorities find out the cause of the latest accident.

The U.S. military says the Osprey is safe but Okinawans have worried the aircraft may be prone to crashes. Anti-U.S. military sentiment is particularly high on Okinawa, home to more than half of about 50,000 American troops based in Japan under bilateral security treaty. Many complain about noise and crime linked to U.S. bases on the island.

A tilt-rotor MV-22 Osprey caught fire after a hard landing on Sunday, killing one Marine and injuring 21 others at Bellows Air Force Station on Hawaii's main island of Oahu.

The U.S. operates 24 Ospreys on Okinawa and announced a week ago that 10 more would be deployed to Yokota Air Base, near Tokyo beginning in 2017.

Officials from six municipalities near the Yokota base have demanded the Japanese government do more to provide information about the aircraft and the accident. Dozens of residents in the area rallied over the weekend to oppose the planned Osprey deployment.
