Japanese Jetstar flight forced to land

A Jetstar flight has been forced to make an emergency landing in central Japan after receiving a bomb threat, according to local media.

The aircraft was travelling south from Tokyo's Narita Airport to Fukuoka on Saturday, when it was forced to divert to Chubu Airport shortly before 8am local time.

No injuries were reported, however footage posted to social media appeared to show passengers disembarking via emergency slides and walking across the tarmac.

Jetstar Japan confirmed the aircraft had been diverted due to a "potential security incident".

"Out of an abundance of caution, passengers disembarked via emergency slides," a spokesperson said.

"We know this would have been distressing for passengers and thank them for their co-operation."

Public broadcaster NHK, which reported the incident as a bomb threat, said 149 passengers had made reservations for the flight.

The broadcaster also reported the emergency landing prompted Chubu Airport to temporarily suspend take-offs and landings.

Jetstar Japan said it was working to support and redirect passengers as quickly as possible and local authorities were investigating the incident.

Jetstar Airways has stakes in sister airlines Jetstar Asia Airways and Jetstar Japan, which is joint owned by Qantas, Japan Airlines and Tokyo Century Corporation.
