Oshino Hakkai
Oshino Hakkai ("eight seas of Oshino") is a set of eight spring-fed ponds in the village of Oshino, filled by snowmelt from Mount Fuji filtering through volcanic rock over decades. Designated a Natural Monument of Japan and part of the Mount Fuji World Heritage listing, it's one of the few Fuji-area stops where the mountain's water, not just its view, is the draw.
What the ponds are
Groundwater from Mount Fuji surfaces here after years of filtering through the mountain's volcanic rock, producing exceptionally clear, cold spring water. The ponds are scattered through the traditional village rather than in one park, so visiting means a walk between them.
What else is in the village
Thatched-roof buildings, small museums, and food stalls selling local specialties sit alongside the ponds, giving Oshino Hakkai a village character that pure viewpoints like Chureito Pagoda don't have.
Cost and getting there
Entry to the village and most of the ponds is free; a short trip from Kawaguchiko by local bus (part of the Kawaguchiko sightseeing bus network) or as a stop on most Mount Fuji day tours from Tokyo.
