I am a frequent business traveler to Japan, since the early 1990's. I am well aware of the standard of accommodation provided in Japan, especially in Tokyo/Osaka - rooms are always smaller than found in the US or Europe, or even other parts of Asia. I was attending the Sumo tournament in Tokyo for several days, and decided that a hotel closer to the stadium was preferable to my usual digs in Shibuya or Shinjuku.
I booked this hotel via a "discounter" website, although the price was not particularly low. For some reason Japanese hotels, despite the worldwide travel downturn, are slow to discount to more affordable levels consistent with their occupancy. A non-smoking room was requested, although I was to find out that no such rooms are available in this hotel.
And despite my expectations of a "small" room, these were the absolute smallest rooms I have ever experienced in Japan, except for the infamous "capsule" hotels. The room was 6 feet wide by 9.5 feet long, plus the standard prefab plastic bathroom. There was absolutely NO WHERE to put the luggage except on the floor, stepping over it each time you wanted to go to the bed/desk.
And there were NO international television channels available at all, nor the usual "bilingual" feature that is usually available for some local television (news). Internet service was wired with no wifi available, but extremely fast without any blocks of VPN or other business services.
Air conditioning was barely adequate, and I would guess not adequate when it becomes hot as Tokyo does in the summer. The one window did open, but high noise levels from the freeway made leaving it open impossible.
Staff spoke virtually no English. Not a consideration for a frequent traveler, but perhaps for someone visiting for the first time.
The free breakfast buffet was perfunctory, but did include scrambled eggs and some kind of mystery meat. Smokers still in the restaurant however required requests to stop. The "non smoking" in public areas concept is still in its infancy in Japan.
Transport to/from the hotel was very good with the JR station just across the road providing direct access into the city center as well as the airport (with only one quick train change).
