忍野八海（おしのはっかい）は、山梨県南都留郡忍野村にある八つの湧水池の総称です。富士山の雪解け水が長い年月をかけて地中でろ過され、澄んだ湧水として湧き出したものです。池はそれぞれ「出口池」「御釜池」「底抜池」「銚子池」「湧池」「濁池」「鏡池」「菖蒲池」と呼ばれ、国の天然記念物および名水百選に指定されています。透明度が高く、四季折々の風景とともに美しい水景が楽しめるため、富士山観光の人気スポットとなっています。
Oshino Hakkai is a group of eight spring-fed ponds located in Oshino Village, Yamanashi Prefecture. The ponds are formed by the snowmelt from Mt. Fuji, which is naturally filtered through underground lava over many years before emerging as crystal-clear spring water. Each pond has its own name: Deguchi Pond, Okama Pond, Sokonuke Pond, Choshi Pond, Waku Pond, Nigori Pond, Kagami Pond, and Shobu Pond. Oshino Hakkai is designated as a National Natural Monument and selected as one of Japan’s Top 100 Exquisite Waters. With its remarkable water clarity and beautiful scenery throughout the seasons, it is a popular sightseeing destination near Mt. Fuji.
