Wonderful onsen retreat
Great for families looking for some traditional serenity. Tucked away with ability to book private onsen. Yes as a base when exploring Hakone, but get ready to walk.

Must stay in Hakone for a Japanese experience
Beautiful onsen, very hiddrn and quiet. Seems like an authentic Japan experience for foreign travelers. Wonderful private hot spring baths. Choice of western or Japanese slerping arrangements. Ie. Beds or futon mats on real tatami floors. The dinner and breakfast alone are worth the stay. Staff is very friendly and helpful. Especially when navigating cultural differences.

The staff was wonderful. Kind, eager to help and make sure guests were taken care of. We had a wonderful dinner and equally excellent breakfast. It’s a small quiet place out of the way, and it felt private and peaceful. The onsen reservation system was simple and we got lucky to get multiple chances to try indoors and outdoors. We had a great experience.

Another wonderful and relaxing stay
This is my third stay at Ajisai Onsen Ryokan, and my first with my family. I really enjoy coming here for the spacious and comfy room, relaxing private onsen, tasty traditional dinner and breakfast, and kind staff. Whenever I visit Japan, I try to make a stop here to wind down. Looking forward to booking here again.

Amazing! I loved the private booking of the three different onsens. Very family friendly. Front desk host was super helpful, spoke sufficient English, was very kind and thorough. My kids loved the whole experience. The beds were very comfortable. Room service was also available. Check in early to get the most benefit for reserving the onsens.
