I think that this is a great resort. The only little problem was that the faucet on the sink was difficult to use. I had a hard time washing my face because it was automatic. However, the faucet in the toilet was not automatic. But the place definitely gets a 100 points if the toilet fittings were automatic, and not the sink ones. + More
This time it was my second time here. Although it is a small accommodation, it’s quite relaxing as a secluded resort for grown ups. The room staff also showed a good sense of formality, and their service and food was very satisfying. Having only stayed in resorts with attached open-air baths and such, and considering the cost, I think this one was the best! I've decided to make this my go-to resort in Hakone. Their meal makes for a good diet for people who drink alcohol. It was such a great meal that almost beckoned me "Come back for another drink", as I was leaving. Thank you for helping me out! + More
I got here by taxi, and could feel the goodness here. It is probably because there are few rooms in here that there weren’t many staff members. However, everyone I met was nice and friendly, and I was impressed. We got a room with an outdoor bath, but we tried another bath in the hotel at first after we arrived that also had a powder room. In it, instead of having a wide variety of products, it only had a simple shampoo, conditioner and body-soap. My friend and I both agreed that simple things like this are perhaps better than fancy ones. There is an open air bath for the people who choose a room without an attached open air bath, so many people use that bath. I was able to enjoy a nice scenic view from the Japanese room, relax in open-air baths and experience the atmosphere of Japanese and western style room, all in a one night stay. They had some creative Japanese food, but nothing special but I could certainly feel the ingredients in there. Everything was quite delicious. I think that the amount was also just right. Since the room staff also told us about local information and the recommended season for a visit, we took a walk to the station on our way home thinking that we’d come visit again at the right season. All in all, I was able to share a nice time with my friend. My buddy also quite liked the resort. Thank you very much. + More
Their baths, meals and guest rooms, everything satisfied me more than I expected! It was quite a pleasant discovery that such a resort for grown-ups was also in Hakone. The food was very delicious. Having had traditional Japanese food on the way, there was also a continental style arrangement and it was delicious too! The range of products and arrangements is quite wide, and yet everything was perfect. I could feel that they have a very talented chef. And not only for dinner, they also had some great items in the morning. I was grateful to have my favourite homely breakfast. Personally I found it comfortable that the guest room was well lit. Indirect lighting was used nicely, and the atmosphere was good. The spots close at hand were bright, it was perfect for my long-sighted eyesight! With that said, I want to visit again. + More
I was looking for a relaxing lodging for my journey. From the mountains to the view of the stars from the attached bathroom, everything was wonderful. The bar also had some casual products, it was a nice luxury space. I would like to revisit, but this time I’m gonna pick a really cold day. + More
