This lounge is located close to gate 15 in the international terminal 1.
The lounge is bright and airy thanks to its long, narrow design with windows on the far side. This also allows some opportunity to watch planes outside. It can feel quite crowded at times.
There are a decent number of seats given the space although they are mostly single, slightly boxy seats so would not be very comfortable for a long period of time.
There is a fair selection of hot and cold drinks, as well as some food. The food is not amazing for an international lounge, but it is better than many other Japanese airport lounges.
There are no showers. There is a smoking room.
Overall this is a functional lounge and an alright place to pass a little time before a flight, but it is not somewhere one would likely want to pass many hours.
