Members of New Acropolis Yokohama in Japan visited a limestone cave.  As the train slides into the Okutama area, the scenery changes completely and becomes a green world full of life.  You can feel the life energy of the trees from inside the car, and it makes us want to walk in nature as soon as possible. Before boarding the bus from Okutama station, we went down to the river and had lunch while soaking our feet in the cold water. We could realize that the clear flow of the river gives a different energy to that of the sea.

In the limestone cave, rainwater melts the limestone in the ground little by little, creating cavities, and the melted water creates icicle-like stalactites.  It takes 150 years to become a 1 cm stalactite.
