10/10 Exceptional

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.

Zahi, 1-night trip

8/10 Very good

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!
Ryan, 2-night trip

10/10 Exceptional

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.
Christina, 2-night trip

Being far away from the hustle and bustle of the surrounding area truly elevates the experience. The room was clean & comfortable and the hot spring was perfect.
Harrison, 1-night trip

A wonderful traditional ryokan. Clean, with private onsens you can use twice per day (or more). Very friendly staff. Highly recommend! Tip: take a taxi from the train station, it is a 15 min walk but very uphill. Also, for fine dining you can walk 10 minutes to the Hyatt that has two nice restaurants incl. sushi.
Anna, 2-night trip

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.
Philip, 1-night trip

Clean and quiet. Japanese breakfast was excellent. Not too many dining options, need to take taxi or bus. Absolutely gorgeous surroundings.
JI SUN, 2-night trip

10/10 Exceptional

Loved our time here. After a night in busy Tokyo, felt rejuvenated by the hot bath, friendly staff, and relaxing atmosphere. First time to Japan for my wife and 3 young kids, the Hakone area and Ryoken plus Onsen experience was a great adventure.

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.
Paul, 1-night trip

10/10 Exceptional

This was our luxury stay in Japan. We absolutely loved the traditional ryokan and the private onsen was just dreamy. We had the option to book an hour every morning and evening—we just booked in the evening because in the morning we are usually ready to get our day started (and I think the bookings started maybe at 8am?). We loved the little walk down the hill to the train station—it was a pretty walk. While in Halone, Gora Park is a MUST—it is so beautiful and there is so much to see. I’d also recommend the Hakone Free Pass, which covered all of our transportation, the visit to Gora Park, and lots more! We’d definitely stay here again!
The view from our window that overlooked the walkway to the front of the hotel.
Room service—shrimp rice, butter chicken, and vegetable curry. It was all delicious!

Fast responses to questions. Able to add extra onsen sessions. Had dinner and breakfast with were both excellent and plentiful.
