A Hawaiian Airlines flight made an emergency landing in Tokyo, its second such incident in Japan this month, an official said on Thursday.
Flight HA 442, which departed the northern Japanese city of Sapporo for Honolulu, made an emergency landing at Narita airport just outside the Japanese capital at 10:53 pm Wednesday.
The pilot cited an abnormality with the Boeing 767's hydraulics system, said an official at Narita International Airport Corp.
None of 248 passengers and crew members on board the flight suffered injuries, he added.
"A signal indicating a possible problem came on," prompting the pilot to make the emergency landing, the airline's Tokyo-based spokeswoman told AFP.
She could not immediately elaborate, but did confirm that the Boeing 767 was scheduled to fly to Honolulu later on Thursday with passengers.
The incident was the second emergency landing in Japan in nearly 10 days by Hawaiian Airlines.
On July 18, flight HA 458 returned to Tokyo's Haneda airport after cockpit signs indicated a potential problem with its hydraulics system and made an emergency landing.
No one was injured at the time, but eight of the jet's 10 tyres burst as it landed, with some oil leaking onto the runway.
