Mount Odaigahara, straddling the Nara–Mie border deep in the Yoshino-Kumano National Park, is one of the wildest and most beautiful high places in western Japan — and one of the rainiest spots in the whole country, which cloaks it in lush, moss-draped primeval forest. A road climbs to a trailhead at around 1,570 metres, from which well-made loop trails (including boardwalks over fragile terrain) lead through ancient woodland, past the dramatic Daijagura cliff viewpoint with its vast panorama, and to the summit of Hidegatake. Accessible yet genuinely wild, it offers some of the most rewarding and least crowded hiking in the Kansai region.

Tips
This is a genuine mountain hike, so wear proper boots and rain gear — Odaigahara is one of Japan’s wettest places and weather turns fast even in summer. The access road is only open roughly late April to November, so it’s a warm-season trip; a car is essentially required. Start early to complete the loops comfortably and enjoy the cliff views before afternoon cloud rolls in.
