Don't be disappointed.... Narita is the home port of JAL, and their lounges are 3rd world. I am a regular user of the one out in the island pier. Access it via an elevator last cleaned when Narita was constructed in 1970. Chairs are crowded in together. No need for tables, because there is no food other than peanuts sort of stuff. There are 2 (yes, count them, 2) business workstations. It's amazing that this dross is in the same general region as what is on offer in Hong Kong, Singapore, KL etc. No comparison.......
