Shojiko Onsen is a secluded hot spring on the shore of Lake Shoji, the smallest and most tranquil of the Fuji Five Lakes in Fujikawaguchiko town, Yamanashi Prefecture, offering intimate views of Mount Fuji without the crowds that characterize the more accessible Kawaguchi and Yamanaka lakes. The bicarbonate thermal waters provide skin-softening and gently restorative benefits, complementing the reflective, peaceful atmosphere of this lakeside retreat where the primeval Aokigahara forest stretches to the lake's southern shore. The combination of volcanic lake scenery, ancient forest mystique, and thermal relaxation makes Shojiko Onsen one of the most atmospherically distinctive hot spring experiences in the greater Fuji-san region.
Insider tip — Shojiko is the smallest and least touristed of the Fuji Five Lakes, preserving an uncrowded atmosphere rare in the Fuji area, and its onsen offers serene bicarbonate soaking with a forested lakeshore setting. The compact lake reflects Mount Fuji cleanly on windless mornings, creating mirror images that draw photographers from across Japan. The absence of large resort hotels means most bathers are local inn guests seeking genuine rest rather than spectacle.
