The Japanese government is considering taking swift action following the reported crash of an Osprey in the country's southwest. Possible moves include a request for the temporary suspension of flights of the US military transport aircraft in Japan.

The aircraft reportedly crashed into waters off Yakushima Island in Kagoshima Prefecture on Wednesday afternoon. So far, what appears to be wreckage has been spotted near the site, and a person has been confirmed dead after being rescued from the sea.

The US Air Force Special Operations Command said eight people were on board the aircraft, which belongs to the US Yokota Air Base in Tokyo. Japan's coast guard and others are continuing search and rescue operations.

Japanese Prime Minister Kishida Fumio said on Wednesday night that the government will do its utmost to save lives. He added that he will seek cooperation with the US military to figure out what actually happened and will consider taking action.

Sources close to the matter say possible government action includes asking the US side to temporarily suspend Osprey flights in Japan.

The government plans to make its final decision after getting information from the US on what led to the incident.
