The Ajisai onsen Ryokan exceeded our expectations. The onsen is great especially since it is private . The most unforgettable experience we had was the dinner. The presentation of kaiseki course was simple and yet very entertaining. The staff were so great of course.

We had such a wonderful time that we didn’t want to leave this place! Our room was lovely and the onsen were amazing. There were plenty of time slots available and the staff was so helpful and kind especially with my young children. They even brought my 3 year old some crackers to cheer her up when she was cranky at breakfast. There are toys available in the lobby. It really feels like they thought of everything! I’m so happy we were able to have this first experience at a ryokan as a family.

This was a unique experience. The 2 indoor and 1 outdoor onsen were very relaxing. The staff were extremely friendly, polite and helpful. The traditional Japanese food was beautifully presented and tasty. The standard of cleanliness was exceptional. About 25 minutes walk from Gora station if you are dragging heavy cases up the hill! Otherwise about 15 minutes.

Traditional Japanese onsen. The only issue iir is in the middle of nowhere and impossible to get any kind of cab or uber in the morning to go to your next destination. Everything at the hotel was great. Service is great. People are extremely kind and helpful, lovely staff!

Beautiful Ryokan. Peaceful and very serene. I enjoyed walking around the town, visiting the Rose Garden, and eating at local eateries. I would highly recommend this Ryokan for people wanting the onsen experience, as you can request it privately. That was the main reason why I chose this onsen. I highly recommend this Ryokan.

Ajisai Onsen Ryokan presents beautifully. The grounds fit in with the surrounding forest landscape, creating a sense of serenity. The staff were friendly, attentive, and accomodating of various requests, including changes to private onsen access on days when we were engagin in Hakone and Gora's experiences. The ryokan is well situated, close to Gora station and cable car, however, it is a difficult walk due to the general steepness of the area - especially with larger luggage or walking with small children - a taxi is recommended by the facility and myself alike. The waters of the onsen themselves are hot, but not so hot that young children cannot enjoy the experience too. In terms of dining, the breakfast options are traditional or western, and children amd babies are catered to as well. Overall, a fantastic experience, and I look forward to the opportunity to return in the future!
