An onsen of pure natural water. The water is used as is. That is really unusual even in Japan.
All in Kyushu
Sendaitaki Onsen "Kyodoyu"
One of the favourite onsens of Takamori Saigo.
Óta Kósen
Bathing in this water might cure health problems. Even a doctor regularly comes to this kósen.
Momiji Onsen
The water quality is excellent. The contrast of green water and orange tiles is rustic but charming.
Hajjiri Kósenyu
We found an unknown kósen in the middle of the mountain.
Fukiagé Onsen "Shinyu Onsen Ryokan"
The colour is like a green tea, black depositions swaying in the water look like tea leafs.

The water contains rich iron, which makes the floor colour orange.
