First of all, this is small ryokan only 7 rooms. People called it dated accommodation but it's just the way we like it. We don't want brand new ryokan, we want something old but clean and well maintained.
How to get there?
From Hakone Yumoto Station take Hakone Tozan Train, you can bring your big luggages inside just fine. Drop at Gora Station then take Hakone Tozan Cable Car. Take the cable car and get out on OH 58 Koen-Shimo. Go downstair a little bit, there is a T section right in front. Go right and walk about 100 metres, take right on 2nd intersection. It's going down hill about 20-30 metres. Or just use google map. This is the best way and shortest way if you carry big luggages with you like us. You don't need to carry your luggages up hill 40 degree up, it's very challenging.
Onsen
They actually have 3 baths, 2 baths are public men and women, they switched them at certain time. As usual you notice it from the blue and pink flag. There is another one which is private onsen in which you book early when you check in and you have 30 minutes of private onsen. It's semi outdoor but without shower so you, first, take a show in the public onsen and then get inside the private onsen. A little bit ackward but it's alright.
On this particular onsen, the water is whitish due to strong content of sulfur. I guess it's near owakudani.
Food
Absolutely fantastic, it's art and delicious. Come empty, it's big dinner and breakfast. Try Yumesho and Hakone Beer.
