Oze
Map
Oze is Japan's largest mountain wetland, spanning the four prefectures of Gunma, Fukushima, Tochigi, and Niigata. Centered on Ozegahara (about 1,400 m above sea level) and Lake Ozenuma (about 1,660 m), a lake formed by a volcanic dam, it is registered as a Ramsar wetland. Precious plant communities such as skunk cabbage and sphagnum moss spread across it, and it is also known as a symbol of Japan's nature conservation movement.

History & Origins
It was designated in 1934 as part of Nikko National Park, and in 2007 was newly designated as the independent Oze National Park. From the 1950s onward, as the birthplace of the movement against dam construction and the take-your-trash-home campaign, it became a symbol of nature conservation in Japan.
Highlights
The skunk cabbage colonies that turn the wetland white from late May to mid-June are the biggest highlight. You can also see large colonies of Drosera anglica (long-leaved sundew), which are rare even in the world. In October, grass autumn colors dye the entire wetland golden.
Visitor Guide
Wooden boardwalks are laid through the wetland, so it can be explored in rubber boots or trekking shoes. Because private cars are restricted, shuttle buses and mountain buses are used. Staying the night before at a mountain lodge is comfortable.
Best Season
Late May to June, when the skunk cabbage blooms, is the most popular, but October, with its grass autumn colors, is also splendid. In midsummer, July to August, a variety of alpine plants can be enjoyed.
