Guide to garden and hotel facilities at Hotel de Yama in Hakone and Lake Ashi.
- Hakone Lakeside, Hotel de Yama TOP
- Facilities
An upscale resort life created
by history and nature.
Our consistent service as a classical hotel and the beautiful garden throughout the four seasons are among our greatest charms. Our in-house hotspring can be enjoyed at the big public bath "Tsutsuji no yu" and our healing spa "Montagne" is there for your upscale resort life.
In Hakone, there has been an old theory that says "there is no hotspring water where you can see Mt. Fuji and Lake Ashi."
At Hotel de Yama, we have turned this theory on its head by having our in-house hotspring "Tsutsuji no yu" from Lake Ashi hotspring. Our hotspring is called "Tsutsuji no yu" and it comes from the tsutsuji (rhododendron) flowers in our garden.
The hotspring water is a simple alkaline water and is known to be great for your skin. We hope you will enjoy our natural hotspring with no additives.

A bright and open bath, with a healing space
as if you were bathing in the forest.
With a modern big public bath that creates a refleshing feeling, we have glass panels reaching from the ground to the ceiling. The big public bath and open-air bath are separated by glass, so a feeling of spaciousness can be enjoyed. We hope you will enjoy it while looking out to the cypress grove.
