Takanabe Wetland is located in Takanabe-cho, Koyu-gun, Miyazaki Pref. In 1968, when Takanabe Disaster-Prevention Dam construction was completed, spring water in the mountain forest pooled into the place where sediment was brought out for the construction and formed the wetland. The wetland area was arranged into a park and open to public in 1998. The wetland is composed of the two parts; the eastern wetland and the western wetland. The promenades of the both wetland part are connected by a hanging bridge named Tonbo-no-hashi (the Dragonfly Bridge).
The wetland is the habitat of a variety of flora and fauna including insects, especially dragonflies, and over 300 species of plants such as Habenaria radiata, which reminds us of an elegant egret, bladderwort, which looks like an ear pick, and a very rare species of barberry that can only be found in the area around Ise Bay and this area of Takanabe and Kawanami towns. Although it is less than 40 years since the wetland was formed, its vegetation has begun to be well-established and attract the attention of the ecologists.
