Wakayama Travel Guide

Oishi-kogen is a highland area that straddles Kimino and Aridagawa. It is famous for its large expanse of Japanese pampas grass which is said to be the finest in the Kansai region. The grass-covered plain spreads across the area's gently sloping summit which peaks at 870 meters. In Autumn when the sun shines over the plain, it takes on the appearance of a vast, golden sea and is utterly enchanting. The peak also offers a 360°panorama with views that stretch as far Rokko, Awaji, and Shikoku.
