JAL Sakura Lounge

Very Ellis Island, jam-​packed and joyless. I shall now take back everything nasty I’d ever said about the United Club (!) and the China Airlines (!!) lounge, both of which at least offer some elbow room and clean air.
Since the JAL flight departure times are so late at night, you should consider:
* Going over to the Cathay Pacific lounge. Their flight departure is about 20 mins earlier, but they have a lot more room, and the hot Noodle Bar is fun.
* The concourse will be completely empty at this hour, with gobs of space to stretch. And the terminal WiFi will have way better throughput than the dismal lounge

Decent but old-​feeling lounge.
The food provided is great for what they are, but limited to sandwiches, onigiri and snacks. Limited but good drinks selection, and great service.
Got pretty busy but not completely full; layout feels a bit cramped and there are not enough plugs. Other oneworld lounges in this concourse: BA (good, but closed late at night) and Cathay (looks new and nice from the outside but I haven’t been inside; separate business and first lounges).
