Hakone Sengokuhara Prince Hotel 箱根仙石原プリンスホテル I went for a day-use onsen for 2500 (expensive). The hotel is surrounded by a golf course, so there is this wall at the rotenburo. While standing, you can see the scenery, but once you sit in the rotenburo, you can’t see it. The water is pleasant, both in temperature and because it feels a bit soapy. There are all the amenities, towels, and even mineral water. Overall, it’s disappointing and expensive. You can visit once. Maybe things like kashikiri and the like would be more fun.
