Lake Onnetou !

 by Kazu

 A beautiful blue lake appeared in the woods at the foot of Mt. Meakan-dake. The blue color of the lake  can be seen from the trail on the hillside of Mt. Meakan-dake.

A wild hot spring near the lake nurtured many tropical fish in the pond under the hot spring waterfall until several years ago.

 The tropical fish was brought by some tourists and they got over cold winters until they were taken away from there.
