A runway had to be closed at one of Tokyo's main airports after a Hawaiian Airlines jet punctured its tyres while making an emergency landing.
Eight tyres blew out when the Airbus A330 returned to Haneda Airport after a display indicated a problem in the hydraulic system, Japanese media reported.
None of the 293 passengers and crew on board were injured, and the plane was kept on the runway while workers replaced the tyres.
The runway closure led to Japan Airlines cancelling some domestic flights, and it warned of the possibility of other flight disruptions. Haneda Airport said in a statement on its website that international flights had not been affected.
An aviation expert told Japanese public broadcaster NHK that the brakes may not have functioned properly if there was a hydraulic system problem, causing the blow-outs.
