What’s the highlight of Sumata Ravine?

“Sumatakyo” (Sumata Ravine) is the entrance of the Southern Alps on the Shizuoka Prefecture side.
This area was certified as the “Southern Alps UNESCO Eco Park” in 2014 in order to protect the valuable ecosystem of the vast Southern Alps that spans Nagano, Yamanashi and Shizuoka prefectures.

The highlight of this Sumata Ravine is the beautiful emerald green dam lake and the long suspension bridge over it.

Why is the water emerald green?

The emerald green of the dam lake peeks through the trees, and it feels as if we are descending into the sky.  
This blueness is due to the “Tyndall phenomenon“.
The water of the Sumata River is so clear that you can see the bottom of the river. The fine particles in this water reflect blue light with short wavelengths and absorb red light with long wavelengths. By this phenomenon creates such a beautiful sight.

Oma Dam lake, the source of the Tyndall phenomenon
Depend on the sun shine, the color of the water changes to emerald green.

The other highlight, Onsen Spa

The type of hot spring is an alkaline simple sulfur spring with a pH value of 8.9. There is a faint smell of sulfur, and hot water flowers, that are slimy to the touch, dance in the water. The hot spring’s ingredients dissolve unnecessary keratin on the skin, leaving the skin getting smoother after bathing. For this reason, it is also known by another name, “Bijinzukuri no Yu”. (Hot water that makes you beautiful!)

There is also a day-trip bath, so after hiking, you can enjoy the hot springs and how about transforming beautiful?
