Super huge international airport (it seems to be 1.4km). Some airlines have to walk all the way to the edge, which takes a lot of time.

The boarding procedure (at least JAL) could not be done mechanically, and there was a long line. If you have a JAL gold card, it will be on the priority line, so it is recommended.

Near the JAL boarding gate (Terminal 1), there is a first class lounge called "No. 37" that can be entered with a priority pass. However, there is no special feeling so far, and the atmosphere is similar to that of a Japanese card lounge.

The lounge in Terminal 2 seems to be wider and cleaner, so if you want to spend a lot of time at the airport and want to spend time in the lounge, it would be better to use the ANA affiliate.
