The room was spacious and very clean. The staff were extremely hospitable and helpful. Even when serving us our dinners and breakfast in our room they told us what we were having. The Onsen’s were excellent and very relaxing. Highly recommend for anyone but especially great for couples for the private onsen’s.

I stayed with my partner and his elderly parents. We were so impressed with the quality of the service here. I especially loved being able to partake in the traditional aspects of the ryokan, wearing yukata, sleeping on futon. We loved the traditional Japanese meal package, the food was superb! Thank you so much for hosting us, we left with such fond memories!

Family of four stayed a regular room with very comfortable floor mats. Everything from the staff to the cleanliness and attention to detail was amazing. We really enjoyed the onsen experience including the provided yakats. Easy walk from the train station or a very inexpensive cab. We opted for the half board and that was amazing 7 course Japanese mess worth every yen! We were sad to leave.

The Ajisai Onsen Ryokan was an amazing experience. The hotel is small, quaint, peaceful and the Onsen's are fantastic. There are not enough words to describe the staff. Nagi, Namu, Rubi... the Chef, the cleaners were TOP Notch. Stayed for 6 nights and we ordered the 7 course Kaiseki meal for 5 nights. Delicious can't even describe what we ate. We are already planning a trip back to the Ajisai. The one on one Customer Service relationship is a 10 star in our book. Domo Arigato for soothing our souls,
