Lake Sai, Landslide-dammed lake in Fujikawaguchiko, Japan.
Lake Saiko extends across 2.1 square kilometers within the Fuji Five Lakes system, surrounded by steep wooded slopes at 900 meters elevation.
The lake formed in 864 when Mount Fuji's volcanic eruption generated lava flows that separated one large water body into three distinct lakes.
The Saiko Iyashi no Sato Nenba craft village presents traditional thatched-roof farmhouses where artisans demonstrate Japanese crafts and soba making.
Visitors access Lake Saiko through regular bus services from Kawaguchiko Station, with options for hiking, camping, fishing, and winter sports activities.
Underground waterways connect Lake Saiko to Lakes Motosuko and Shojiko, maintaining identical surface elevations of 900 meters across all three water bodies.
