Oshino Hakkai is an assemblage of eight ponds in Oshino, a small village in the Fuji Five Lake region, situated between Lake Kawaguchiko and Lake Yamanakako on the site of a former lake that dried up several hundred years ago. The eight ponds are fed by snowmelt from the slopes of nearby Mount Fuji, snowmelt that filters down the mountain through porous layers of lava, eighty years in the process, to result in an exquisitely pure spring water that is revered by the locals. The little village of Oshino Hakkai is blessed in its proximity to the iconic Mount Fuji, as well as all the surrounding bodies of crystalline spring water. Yet there haven't always been only the five lakes for which the area is often named (Fuji Five Lakes District). At one time there was a greater body of water, Lake Utsu. Then, about 800 years ago, lava flows from Mount Fuji divided Lake Utsu into Lake Yamanaka and Lake Oshino, and for a while there were six lakes. However, over time Lake Oshino gradually drained away, leaving in its footprint the eight spring fed ponds, the sources of which are the Mount Fuji snowmelt, extraordinarily pure water that filters down through all the petrified lava of the Mount, and wells upwards to the ponds.
