Oshino Hakkai (eight seas) is located in the village of Oshino in the Fuji Five Lake region between Lake Kawaguchi and Lake Yamanaka in Yamanashi Prefecture. The eight spring ponds are Deguchi-ike (exit pond), Okama-ike (pot pond), Sokonashi-ike (bottomless pond), Choshi-ike (Choshi pond), Waku-ike (gushing pond), Nigori-ike (muddy pond), Kagami-ike (mirror pond) and Shobu-ike (iris pond). They are fed by infiltration of snow-melt water, filtered down the mountain through porous layers of lava, and it is said that they are connected through the underflow conduit. Naturally, the water is very clear. Oshino Hakkai is included in UNESCO’s Mount Fuji Cultural World Heritage site (Fujisan, sacred place and source of artistic inspiration), and the eight ponds are 8 of the 25 constituent assets.
