Found within Aso Kuju National Park, Tadewara Marshland is a prime example of an inland marsh. It became the prefecture's first location to be registered under the Ramsar Convention in 2005.
One of the widest everglades in the country, the wetland is positioned in Chojabaru on Iida Highlands 1,000 meters above sea level, as rare vegetations including peat moss flourish here.
Preservation of Tadewara Marshland is credited to Noyaki open burning in the region.
Equipped with a wooden trail, providing a great opportunity for viewing plants of all four seasons
