Guida
Oishi Highland is a prefectural natural park located in Wakayama Prefecture. It is characterized by its vast silver grass (susuki) plains surrounding the summit, making it one of the most significant landscapes in the Kansai region. From the top, visitors can enjoy a breathtaking panoramic view of Shikoku, Awaji Island, and Mount Goman. It is a highly popular destination for hiking, camping, and nature walks.
To maintain this expansive silver grass ecosystem, local governments and NPO groups conduct regular conservation efforts. A notable cultural event is the traditional "Yamayaki" (mountain burning) held around mid-March. This practice is essential for preserving the grassland's ecosystem and serves as a beautiful sign of spring's arrival. Additionally, the area is home to the Miroku Benzaiten Shrine, which features a massive Katsura tree estimated to be 500 years old, designated as a prefectural natural monument.
The greatest attraction is the silver grass field, which changes its expression with every season. In autumn, the landscape transforms into a shimmering sea of gold, offering a truly unforgettable sight. The panoramic view from the summit is another highlight; on clear days, you can see the silhouettes of Shikoku and Awaji Island, providing a profound sense of openness and freedom.
You can enjoy different charms depending on the season. The best time to visit is autumn (around September to October) when the silver grass glows most brilliantly. In mid-March, you can witness the traditional mountain burning ceremony, a unique way to feel the natural cycle of the land. While daytime offers beautiful views, please be mindful of sudden weather changes when hiking or climbing.
Outdoor activities such as hiking, mountain climbing, and camping are very popular here. There are various routes available, ranging from beginner-friendly paths to more challenging trails for experienced hikers. Camping under the stars is also a favorite way to refresh both mind and body while being immersed in nature.
The surrounding area features several spots to enjoy nature, such as the Iwao of Aso, the historic Zao Bridge, and the Toi Campground. Exploring the Kimino Town area will allow you to deepen your understanding of the natural beauty and culture of Wakayama.
