I like NRT. It is my airport f preference when travelling through Japan. Smoking rooms, like in most Japanese airports, are conveinently located. The smoking room in the international concourse of NRT is far more comfy than those in NGA and some of the other Japanese airports. The rooms in Narita actually have seating and are actually large enough, compared to the “aquarium” like rooms in Nagoya. I have always found the Japanese to be especially friendly and courteous while carrying out their duties. This goes for security, clerks and airport officials. They are doing a job but still manage to be friendly and respectful.
