To get to the pool or gym requires an elevator ride, walk across the lobby, separate elevator ride and passing through another staffed room (because the pool has an extra per person fee). My teenage son was not allowed to use the gym, even with supervision.
Massages are not available in the morning and require a separate fee for a proper massage room instead of the bed in your room (beds make poor massage tables in my opinion).
Room had a humidifier, but it brought the room up to 80% rather than a more sensible 60%. It was not configurable as far as we could tell. So we turned it off, but the cleaning staff turned it on again. Likely due to this, the room had a distinct mildew / mold smell (relatively common in Japan). The best hotels I've stayed in here have a humidifier / dehumidifier that keeps the room between 50% and 60% which is comfortable and avoids mold.
Overall, it is in a very convenient location and the room was spacious (we stayed in the family room), but the extra fees were tedious and felt unwelcoming and the room was too humid and smelled of mold. To me luxury is convenience and comfort, not a fancy lobby. This hotel had issues with both.
