Japanese media are reporting that the Ministry of Transport investigation team have reported that there is a possibility the fire began in the RIGHT engine following a fuel leak in the pylon. A ground engineer reported seeing smoke and a large leak from the right engine and advised the crew to evacuate via the interphone.
Looked like the left engine by the ealier photos/videos.
A good collection of photos is available at
