Japan's largest high moor. The highland plateau is covered with numerous small ponds, crowds of creeping pine trees, and virgin forests of beech trees.
Oze spans the boudaries of the four prefectures of Gunma, Niigata, Tochigi, and Fukushima.
Oze, set on a plateau 1,400-1,700 meters above sea level, is the largest high moor in Japan; it was created by the lava from Mt. Hiuchigatake. Numerous wetlands and marshes cna be seen and rare bog plants such as 'Mizubasho' (Japanese skunk cabbage) and Nikko-kusuhe (yellow day lily) grow in patches. Creeping pines growing in stands and virgin forests of beech trees stretch to the nearby mountains. All these areas were designated as a special natural monument of Japan in 1960, and inscribed as registered wetlands under the Ramsar Convention of 2005.
In the colonies of bog plants, trails of logs and wooden planks are laid out as hiking tracks, and mountain huts are available. Lots of visitors flock to the area, especially when the blossoms of 'mizubasho' are at their best in early summer or when the leaves turn red in autumn.
