About
Kinnotake Sengokuhara (Adults Only)
Kinnotake Sengokuhara is a 4-star adults-only ryokan set in the Sengokuhara Onsen district of Hakone, Kanagawa. Each suite comes with its own open-air bath, and the property sits close enough to Hakone Pirate Ship Togendai Port for a day trip to the lake. The hotel is rated 9.4 from 74 guest reviews, with top marks for comfort, service, and rooms.
The ryokan pairs traditional Japanese design with modern amenities: flat-screen TVs, air conditioning, mini-bars, and free Wi-Fi throughout. Guests can use the shared hot spring bath, book a massage, or unwind in the garden. A welcome drink is offered on arrival, and special diet menus can be arranged. Parking and an EV charging station make self-driving straightforward, though note the check-in window is 15:00–19:00.

In brief
What works, what to weigh
+
Strengths
3 reasons to book- Private open-air baths in every suite — The in-room open-air bath is the defining feature, with several reviewers highlighting the rooftop option and its views. It offers a private, serene soak without shared facilities.
- Exceptional comfort and room design — Guests consistently praise the spacious layout, fine craftsmanship, and calming decor. The rooms blend Japanese and Western styles, with flat-screen TVs, air conditioning, and coffee machines.

–
Worth weighing
3 to weigh- Adults-only policy may not suit families — While one review mentions staying with children, the property is explicitly adults-only, so younger guests aren't the target. Families with kids may find the atmosphere too quiet or the policy restrictive.
- Limited transportation options — The hotel is in a mountainous area, and guests note that getting around without a car can be challenging. The staff help with arrangements, but you'll likely need a taxi or rental.
- Strict check-in window — Check-in is only from 15:00 to 19:00, which can be tight if you're coming from a long day of sightseeing or rely on public transport.
