Curfew and closure of of public areas at 9pm. Lobby area could easily be so much nicer. Food was ok, but fully Japanese would be much better (poor attempt on a risotto that was cold and barely distinguishable from mashed potatoes...)
I suppose the location is worth the money... No, it is a pretty decent hotel, maybe one of the nicest in terms of room size, style and view (river and mountains!) I've been to. also the Japanese bath was really nice and staff very helpful. However, the 9pm curfew was somewhat ridiculous - doors were looked AND all lights in the hotel lobby (only place with wifi...) switched off. Lobby area lacks some charm in general - old and no comfy seats. In a hostel this would never even slightly bother me but I paid the same for one night here as I would have for 6 nights in a hostel, so....But, once in a life I suppose, staying in kamikochi directly at the river may be worth it.
