KANSUIRO ANNEX
8,7/10 Excellent - Based on 211 reviews
KANSUIRO ANNEX sits adjacent to the century-old Kansuiro ryokan in Tonosawa, Hakone. The original inn—built in 1919 and noted for its four‑storey wooden tower—anchors a small group of guest buildings; the Annex extends the same traditional carpentry and riverside setting, offering compact rooms and straightforward access to communal baths. Framed by the Hayakawa river and the surrounding hills, the property blends historic construction and seasonal scenery, appealing to visitors seeking a ryokan with onsen in Hakone.
Guest accommodation at the Annex follows a Japanese‑style layout: tatami floors, futon bedding that staff prepare after dinner, low furniture and verandas with stream or garden views. Several room types include in‑room or attached hot‑spring baths, while the property also maintains shared indoor and open‑air baths facing the river; a kashikiri (private rental bath) is available for exclusive use when time slots permit. Meals focus on seasonal ingredients and are delivered to rooms for dinner and breakfast, reflecting a traditional in‑room dining rhythm.
The Annex operates with the same service rhythm as the main ryokan—tea on arrival, room service for meals, and discreet staff versed in Japanese bathing etiquette. Its location is a short walk from local transport and regional attractions, yet the sound of the river and timber architecture create a calm, restorative atmosphere. Suitable for travelers seeking a measured, traditional onsen experience, the property functions as a practical ryokan with private onsen in Kanagawa for guests who want to combine cultural architecture with thermal bathing.

Convenient transport link by bus
Reviewers liked the bus stop directly in front of the ryokan and the easy access to local transport (e.g. to Hakone Yumoto or the cablecar), making the location convenient for exploring despite being slightly set back from the centre.
Negative Reviews
No on-site dinner / limited nearby restaurants
Several guests noted there is no restaurant service for dinner at the ryokan and few dining options nearby; visitors recommended planning meals in advance or returning to a town centre for dinner.
Rigid check-in and breakfast schedules
Multiple reviews mentioned limited or strict check-in windows and fixed breakfast times (often early), with some guests feeling pressured to choose or adhere to strict time slots.
Rooms may lack en-suite bathrooms
Some guests were surprised that certain rooms do not include a private shower/toilet and that bathrooms or toilets are located outside the guest room, which affected expectations for privacy and convenience.
Perceived high price / value concerns
A number of travellers felt the rate was high compared with the services received (citing breakfast options, lack of dinner, insect issues or missing curtains), leading them to question the value for money.
Access and noise issues for some rooms
A few guests reported that the walking route from the station can be narrow, poorly lit or awkward on foot, and that street-facing rooms can experience road noise; insects and missing curtains were also mentioned as nuisances in some rooms.

Yes — the property offers hot spring bathing including public and open-air baths, and Annex guests have access to the main ryokan’s bathing facilities. Bath access may require coordinating with reception.
Private (kashikiri) baths are available and can be used when free or arranged through reception; availability and short reservations depend on occupancy. Using a private bath is a good option for privacy or tattooed guests.
Some public onsen at traditional ryokan maintain restrictions on visible tattoos. If you have tattoos, book a private bath or check with reception on the day of arrival.
The property does not advertise a regular shuttle service. The nearest major airport is Haneda (about 80 km); the usual route is train to Hakone-Yumoto then a short walk or local bus to the ryokan.
Tonosawa Station is very close (around 200 m), and Hakone-Yumoto Station is roughly a 10–15 minute walk (about 13 minutes) or a short local bus ride. The Onsenba-iriguchi bus stop is also within a short stroll of the property.
Standard check-in is between 16:00 and 18:00, and check-out is generally between early morning and 11:00 (confirm specific hours at booking). Please inform the ryokan of your expected arrival time in advance.
The Annex typically serves a morning American-style breakfast; traditional Japanese dinner is offered via the main ryokan and is usually served in-room. Inform the ryokan about dietary restrictions well in advance (they request notification for special needs).
Pets are not permitted at the property. Convenience stores and shops in the Hakone-Yumoto area are within a short walk (roughly 10–15 minutes); dining options immediately next to the ryokan are limited, so plan accordingly.
