About Mount Ōdaigahara#

Mount Ōdaigahara (Odaigahara) is a high plateau and mountain massif on the Kii Peninsula in central Japan, with a summit around 1,695 metres above sea level. It is a significant natural area within Yoshino-Kumano National Park.

The site is prized for high-altitude forest, boggy moorland and a network of marked trails and boardwalks that let visitors access viewpoints without damaging vegetation. Observation decks provide broad panoramas across the Kii Peninsula and are popular in both summer for alpine flora and in autumn for foliage.

The plateau and surrounding forests have long been valued for their biodiversity and scenic importance and were incorporated into Yoshino-Kumano National Park to conserve the landscapes and plant communities. Infrastructure such as trails and viewing platforms has been added to support recreation while protecting sensitive habitats.
