The kongo falls is a small fall located on the foot of Mt. Imakuma.  Most of the people lived in Tokyo may not know this small fall, but it is very impressive. To access in front of the falls, we must go through the tiny tunnel, which is seen in the opposite direction of the falls. At the day I took a picture, the second minor waterfall on the down stream was almost frozen. A small Kongo statue is seen at the left of the falls, which may be the origin of the name of the falls.
