TOKYO — A transport helicopter made an emergency landing after catching fire on Wednesday in a United States military training area on the northern part of Okinawa in Japan, stirring concerns about the deployment of the craft near civilian areas.

In a statement, the Third Marine Expeditionary Force said that the helicopter had been taking part in a routine training and that none of the crew members or any civilians were injured.

According to the Japanese Defense Ministry, the helicopter, a CH-53, made its landing in the Takae district of Higashi village, where the Japanese government has been building helicopter landing pads for the American military, a project that a small but fierce group of residents have been protesting for years.

NHK, the public broadcaster, quoted the United States military as saying the helicopter had been stationed at the Futenma air base on Okinawa.
