How to get to Oze National Park

About Oze National Park

Oze National Park is a national park that spans Fukushima, Tochigi, Gunma and Niigata prefectures in Japan. The park’s mission is both to protect the natural environment and to provide sightseeing, with Oze, the largest mountain wetland area in Japan, and the surrounding areas such as Aizu-Komagatake, Tashirozan and Taisaiyama as viewpoints.

Oze was formed when lava from Suidake was intercepted by the Monomi River, and is located at an altitude of 1,400 to 1,700 meters, making it the largest high-rise wetland area in Japan. Among the approximately 400 shallow ponds scattered in Oze, you can see wetland plants such as the rare wetland plant Kannon lily and the Nikko yellow sugo (a yellow lily), as well as floating islands formed by floating peat layers. From spring to summer, various flowers in the Oze wetland area compete with each other, and the clear air and beautiful scenery make people come back for more.

In addition to the beautiful scenery in the wetlands, it is also worth visiting the Aizu-Komagatake, Mount Taisai, and other mountain scenery in Oze National Park, especially the large jungle of fusuma pine and beech native forests, which undulate spectacularly when the wind blows.
