[khedoros1]

When I visited, I stayed in a business hotel in Ikebukuro, a ryokan near Chidorichou station, a youth hostel in Kyoto, and a hotsprings hotel in Hakone.

The business hotel's room was tiny (as described by the person your replied to). The ryokan's rooms were a very nice size. The hostel's were tiny (either 4.5 or 6 tatami?), but the bathrooms were down the hall, at least. The hotel in Hakone had decently-sized rooms, but not as large as the ryokan. I don't remember them being any more cramped than when I've visited cities in Europe, anyhow.
