History

Early Developments

In 1903, the first hydroelectric dam was proposed in Oze, sparking industrial interest in its natural resources. By 1934, Oze was recognized for its ecological value and included in Nikko National Park.

Conservation Initiatives

Conservation efforts began in 1949 with the founding of the Oze Conservation Association, which opposed industrial development. In 1952, boardwalk construction started to protect the fragile marshlands, followed by the designation of a Special Protection Zone in 1953 to safeguard the area's unique ecosystems.

Growing Popularity and Environmental Challenges

Oze's rising popularity in 1955 led to concerns about environmental degradation due to increased foot traffic, prompting a review of sightseeing road plans. By 1960, it was designated as a Special Natural Monument of Japan, underlining its ecological significance.

Restoration and Management Efforts

Restoration efforts began in 1966 to rehabilitate moor vegetation damaged by human activity. Conservation campaigns in 1971 successfully halted roadway construction, and a 1972 initiative to reduce litter encouraged visitors to carry their trash home.

Continued Conservation Measures

Further conservation measures were introduced in the 1980s, including drainage systems to reduce human impact in 1981, a tipping system for restroom cleanliness in 1985, and mats at park entrances in 1990 to prevent the spread of invasive plant seeds.

Recognition and Establishment as a National Park

Oze gained international recognition in 2005 when it was registered as a Ramsar Convention site for its importance as a wetland habitat. In 2007, Oze became Japan's 29th national park, officially separating from Nikko National Park and covering 37,222 hectares, including Mt. Aizu-Komagatake and Mt. Tashiro.
