The staff was especially helpful and accommodating. The room was clean and suited our party of 4 perfectly. We enjoyed the Japanese dinner (cooking part of our meal on the individual hot plates was different and fun) and breakfast. We liked having a choice of using indoor and outdoor onsen. We would definitely stay there again.

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.
