Japan ordered a halt to all flights of Boeing Co. 777s equipped with the type of engine that failed Saturday over Denver as U.S. aviation regulators ordered emergency inspections of the model’s fan blades.

Japan’s transport ministry on Sunday ordered ANA Holdings Inc. and Japan Airlines Co. to ground Boeing 777 planes they operate following an engine failure that rained debris over a Denver suburb but injured no one.

The airlines had already taken the planes out of service — 13 operated by JAL and 19 by ANA — before the Ministry of Land, Infrastructure, Transport and Tourism issued the order.
