Hakone Fuga – Adult Only
8,3/10 Excellent - Based on 196 reviews
Hakone Fuga – Adult Only presents a calm, adults-only retreat in Sengokuhara that opened in June 2017 and expanded with an annex in 2019 to offer more rooms with semi-exterior bathing. The property is arranged like a small villa collection with roughly two dozen rooms, a non-smoking policy and public areas that emphasise quiet comfort and an adult atmosphere; interiors balance modern convenience with Japanese touches such as yukata choices and a lounge bar. Reservations and arrival arrangements are managed carefully to maintain the tranquil setting.
The onsen facilities are a central feature: a large indoor bath and an open-air bath fed by a sodium-chloride thermal source with set public hours in the evening and early morning. Several guest rooms in the annex include semi-open-air tubs and the hotel offers, for an additional fee and subject to availability, private outdoor spa/jacuzzi options, which make it suitable for travellers seeking a ryokan with onsen Hakone experience or a ryokan with private onsen Kanagawa booking.
Meal service emphasises Japanese breakfast and there is a small bar and lounge for relaxed evenings; advance notice is recommended for dinner plans. Practical conveniences include free Wi‑Fi, onsite parking and an optional shuttle from the local bus information centre by prior arrangement, which helps when visiting nearby attractions such as the Sengokuhara grasslands, the Lalique glass museum and the Pola Museum of Art. House rules and quiet hours are enforced to preserve the adult-only atmosphere.
