We did not actually stay the night at the hotel- we took a daytrip from Tokyo to Hakone, and wanted to visit an onsen. I researched hotels beforehand and this is one of the few that allowed non-guests to use their onsen (for a charge, and you have to arrive before 3 PM according to their website). We bought the Hakone free pass (highly recommended!) and this hotel was right on the Obaku ropeway stop (the only hotel around there from what I could see, very easy to find). We paid our fee (ended up around $15/person) and my husband and I went into the segregated baths. When you first step in, there is a large room with showers, towels, lockers, massage chairs, and beauty/hair products to use. After undressing (yes, completely), you can step into the inside bath or the outside bath, which is what I recommend. From the outside bath, there is an unbelievable view of Mt. Fuji. In the women's bath, they bring complementary sake starting at 3 PM (my husband said this didn't happen in the men's side). We both really enjoyed it and it was a great respite in a hectic 10-day trip to Japan. The hotel was easy to find, the price for use of the onsen was very reasonable, and I will definitely come visit this onsen in the future.
