In brief
What works, what to weigh
+
Strengths
3 reasons to book- Private open-air baths in every room — Each of the 28 rooms includes an open-air bath, so you can enjoy the hot spring in private. Reviews repeatedly call this out as a highlight.
- Excellent service — Staff are consistently praised for being polite and friendly, and one review mentions a special birthday dessert arranged by the team.
- Quiet riverside location — Set not far from a pristine river and green nature, the area is calm and relaxing – still within reach of the Hakone Toy Museum and other sights.
–
Worth weighing
3 to weigh- Check-in only until 19:00 — The check-in window is strictly 15:00–19:00, so if you arrive later, you’ll need to arrange something or miss it.
- Adults-only policy — While this is a feature for some, it means families with children can’t stay here – a deal-breaker for those travelling with kids.
- Not the cheapest option — With a price from £6 per night (likely per person or for a very basic package), the ryokan isn’t a budget choice – you’re paying for the onsen experience and setting.
