An All Nippon Airways Boeing 787 has made an emergency landing in Japan's Takamatsu airport after the flight crew observed an alert related to a battery.
All 129 passengers and eight crew aboard the aircraft were evacuated via slides, says an ANA spokesman.
"An error was coming up for a battery," says the spokesman. "So it was decided to make an emergency landing."
Media reports indicate that smoke was also observed in the aircraft's cabin, but the spokesman was unable to confirm this.
The aircraft, registration JA804A, was operating flight 692 on the Yamaguchi-Ube to Tokyo Haneda route. The aircraft departed Yamaguchi-Ube at 8 a.m. local time and made the emergency landing at 8:47 a.m.
Flightglobal's Ascend Online database shows that the 787, MSN 34486 was delivered to ANA in January 2012.
ANA operates 17 787-8s and has a further 19 on order, and 30 787-9s on order.
The news comes just one week after a battery fire aboard an Japan Airlines 787 at Boston's Logan airport. The Boston fire was a major driver of a US Federal Aviation Administraion review into the 787 announced on 11 January.
