This spring is named "Reibo Spring" because it is blessed water from a magnificent and beautiful mountain. It is said that this spring water has been gushing out after 30 years of rain and snow melt permeating the ground of Mt. The subterranean water that passes through the mountain body, which can be called nature's filtration system, is free to take home with you. It is located along Highway 108 in the Senboshi area on the west coast of Rishiri Island.
