Kinnotake Tonosawa (Adult Only)
9,4/10 Exceptional - Based on 276 reviews
Kinnotake Tonosawa is an adults-only ryokan set in the Tonosawa forest of Hakone, arranged as a small cluster of villas linked by a suspension bridge over the Hayakawa valley. The intimate scale—nine carefully designed rooms—keeps focus on privacy, seasonal views and natural materials. Public areas and room terraces look toward the woods, creating a calm setting suited to couples and travelers seeking a focused onsen retreat; it operates as a ryokan with private onsen in Hakone.
Each accommodation opens onto a terrace with an open-air bath fed from the property's private spring; the operator notes a golden-hued water and offers baths finished in polished Mikage stone or Aomori cypress. Rooms provide seating areas, climate control, a refrigerator and coffee maker, bathrobes and a safe, plus complimentary Wi‑Fi and unobstructed forest or mountain views. Many units are designed for direct private access to the onsen, reinforcing the property's positioning as a ryokan with private onsen in Kanagawa.
Dining centers on seasonal kaiseki menus using local ingredients, presented in a measured sequence; some plans include chef-led or interactive experiences. Facilities include a small spa, a fitness area with pool and sauna, a restaurant and a lounge, while services cover 24-hour reception and parking. The ryokan is a short bus ride plus walk from Hakone‑Yumoto and within easy reach of regional attractions, making it a contained base to explore during the day and return each evening to a private onsen and peaceful woodland setting; the property enforces an adults-only policy.

Remote location and transport constraints
Multiple reviews mention the ryokan is fairly isolated; buses can fill quickly and timing can be tight — guests sometimes recommend arranging taxis or being flexible with schedules to avoid issues.
Occasional language/communication limits
Some guests experienced communication challenges due to limited English proficiency among staff, which in isolated cases caused minor misunderstandings.
Minor room or amenity shortcomings
A few guests suggested small improvements such as better pillows, an extra mirror/vanity, relocating shower toiletries into the shower area, or more snack/ice cream options for the onsen area.
Seasonal insects and night sounds
A couple of guests noted loud frogs at night or large mosquitoes during certain seasons; bringing earplugs or insect repellent was recommended.
Some dated design features in parts of the property
One review mentioned certain design elements (for example dark, windowless corridors) felt dated, though this was presented as a minor issue compared with overall quality.
