JAL just "upgraded" their seat map display in their reservation system used by the Japan region website and the JMB portal. Now they have the same style as the one used on domestic booking (Japan region) and you can see the actual plane and more accurate details. BUT you can no longer tell whether the seat has been assigned or blocked

Note this doesn't affect the "View My Reservations" page seat map yet
Too bad I have to use expertflyer to check that now if I really want to know
