You can either open up these pages using a translation tool such as google's - or just click on the links (usually page 2, 3, 4 etc) it's not too confusing once you get the hang of it. The lady who does these photos will give you a guided tour of the rooms at these hotels - giving a much better indication of what to expect than the Hotel's website.

----------
The Sofitel closed in December 2006 - even the Accor website doesn't acknowledge this
http://sheepcote.jp/rum/hotel/sof-p01.htm - a shame, I always hoped to stay here, but the good rates never coincided with my visits.
I wonder what they'll do with the building now.
