I have been to a number of Onsen before, and had high expectations, which this hotel almost lived up to.
It's a treat getting to Gora, taking the Romance Car from Shinjuku (1 hr 40 mins) and then a small switchback train, running to Japanese precision, up the mountain (about 45 mins). The hotel is really close to the station.
The room was beautiful, and immaculately maintained. A private bath on the balcony makes it almost heaven. Dinner was below average, and could really be given a greater "wow" factor - get a really great chef in to re-make the dining experience! Breakfast was better, and the Japanese breakfast was generous and delicious.
There are three private baths as well, but we didn't try them - huge storm the night we were there which we watched instead.
I think where I'm disappointed is that the place seemed stage managed, rather than the service coming from a delight in service. While all staff were faultless, they were young and probably working a part-time job. I suppose more heart would make this place wonderful!More
