The Land, Infrastructure and Transport Ministry started three days of inspections Wednesday of Japan Airlines to verify whether the airline has implemented promised preventive measures following a series of safety blunders.

More than a dozen ministry officials received a briefing from JAL safety promotion officials at the airline's headquarters in Shinagawa Ward, Tokyo, in the morning before inspecting the operations control room overseeing all JAL flights.

The inspection will include a visit by the ministry officials to JAL's hangars at Haneda airport to see whether the airline has properly carried out maintenance and aircraft repairs, properly trained its employees on safety matters.
