We stayed as a family group of 5 adults with evening meal and breakfast. Probably the best traditional meals we had in a 2 week visit to Japan (including a wedding reception meal @ £180 a head).
It was expensive but well worth it!
The Shabu-Shabu evening meal (with the boiling pot in the centre to cook your own meat etc) was delicious, and since we could have endless refills of the meat, rice, and salad dishes, well worth the price.
Breakfast was an excellent selection of traditional dishes, closely followed by another visit to the baths (separated sexes), which were scrupulously clean and maintained.
The staff went out of their way to help us, at any time, day or night.
Modern construction - decorated to look like a traditional Onsen, but with the advantages of modern plumbing and soundproofing.
The only thing that I personally did not like was the Futons, but this was quite expected, as I had trouble with most hotel beds in Japan as they were all hard!More
