This a small Ryokan which is very authentic Japanese style. No English spoken but this adds to the authenticity. We loved the natural accommodation which was exactly as shown on the website. Excellent meal provided in the evening and an enormous breakfast which we were not expecting so was a bonus. We lounged about in out Japanese clothes provided and Thoroughly enjoyed our visit to this clean and peaceful retreat.

Yamagaso was a wonderful surprise after a very disappointing stay the week before at Arima Onsen. This property is beautiful and our room with a garden view was more pleasant than any any place that we’ve stayed around the world. The rooftop onsen is a very special experience to not miss. The breakfast and dinner was superb and each dish presented was a work of art. All that being said, what made this place really stand out was the service provided by Kimiko. Her attention to detail, explaining customs, preparing the room and serving meals made our experience very special

The stay at Yamagaso was a unique experience. I recommend doing the half board as the Kaseiki dinner and the breakfast were fantastic! We also love the private onsen and the convenient access to the other onsen at the hotel next door.

A lovely authentic Japanese experience. Very welcoming hosts. Food was plentiful and to a high standard just not to my Western palate. Very fish orientated. A menu would have been good to help identify some of the dishes. We loved getting dressed into our Yukatas. No Wi-Fi in the room but available in the lounge. Convenient for Hakone station.

We had a fantastic stay at Yamagaso. We were able to drop our bags off at the main hotel so we could go sightseeing before check-in. Dinner was a delicious kaiseki meal served in our room. It was great having our own private bath in our villa with hot spring water. Our host Momo-san was sweet and very helpful. If we ever return to Hakone we would love to stay here again.

This place blew us away! We stayed in the Yamagaso annex in the Chouji room. The area was great, a nice walk or bus ride from the station. Then the room, we were very impressed! Traditional style with the tatami mats. We had the half board which included breakfast and dinner. The amount and variety of food was spectacular! The staff were super friendly too, everyone we met was great! We used the private bath, public bath and the outdoor bath at night which were all very nice and relaxing. I'm not sure how this place could be any better for a relaxing few days in Hakone, would definitely come back every time!

My experience at Yamagaso was amazing. The service was beyond exceptional, the staff pay attention to every single small and big detail. My family felt they staff really cared for each of us (my teenage boys had so my gratitude for how they showed us around the onsen and explained the traditions). If you are looking to experience a traditional onsen, Yamagaso wil give you that. The property is beautiful, I felt the pictures cannot capture the beauty until you see it for yourself. We were able to use all the baths (actually had them to ourselves most of the time!). The food was amazing. They served traditional set course meals and it was very large portions, you will not be hungry for days afterwards! We are willing to try all foods , so we appreciated eating traditional dishes that are very different. The property is easily accessible from Yumoto station, they staff helped give us directions to take one bus and inform the bus driver where to stop. They had a shuttle service for departing the onsen back to the train station. Overall Yamagaso was an experience of a lifetime and probably the best thing our family experienced in Japan…of all vacations we have ever done. If I could rate this place 100 out of 10 I would! Thank you to the staff for making this so special and making a dream come true!
