Boeing released a statement following the incident:
We are aware of the 787 issue that occurred Tuesday afternoon at Narita, which appears to have involved the venting of a single battery cell. The issue occurred during scheduled maintenance activities with no passengers on board. The improvements made to the 787 battery system last year appear to have worked as designed. We sincerely regret any impact caused to Japan Airlines and are working with them to return this airplane to service.
