A Japan Airlines flight bound for Sydney was forced to turn back after takeoff when a business class passenger seat caught fire, according to reports.

The small fire was apparently caused by a cigarette lighter -- although the airline said it has not yet identified who it belonged to, according to the Kyodo News and Jiji Press news agencies.

The Boeing 777, carrying 260 passengers and crew members, took off from Narita airport near Tokyo on Saturday evening but turned back shortly after takeoff.

No one was injured in the incident but passengers were forced to stay in Japan overnight, the reports said. The airline was not immediately available for confirmation.
