Moss Walk

Oirase Stream, designated as one of Japan's Precious Moss Forests, features a landscape where everything from trees to rocks is covered in moss. Within its deciduous broadleaf forest, a scene reminiscent of a natural moss garden unfolds. The “Moss Walk” is a small-group guided tour that explores the natural history and ecosystem of Oirase's forests through its signature mosses, allowing participants to enjoy nature's charm. The tour offers two options: a morning tour (180 minutes) for those wishing to leisurely immerse themselves in Oirase's nature, and an afternoon tour (90 minutes) for a more casual experience. Using a magnifying glass, you'll discover the beauty and diverse designs of moss, guaranteeing new discoveries and moments of wonder. Additionally, Oirase Stream is a scenic spot designated as a National Natural Monument for its beautiful mountain stream and is also famous as a popular photo spot.
