Kitagawa marshland is a wetland spreading in the Eda and Kawasaka districts of Kitagawa-machi, Nobeoka City. Several-minute drive from Kitagawa Interchange (Roadside station, Kitagawa Hayuma) on the Higashi Kyushu expressway, the two bogs of Eda (18ha) and Kawasaka (2ha) are collectively called Kitagawa marshland.

It has been designated as a candidate wetland under the Ramsar Convention (by the Environment Ministry in 2010), a critical habitat in Miyazaki Prefecture (in 2008) and a critical wetland in Japan (by the Environment Ministry in 2001). Home to more than 50 endangered species of fauna and flora, the marshland is of very high academic value.

Kouhone is a nymphaeaceous plant representing the land. More than 1000 lilies of this kind grow in Eda and Kawasaka rivers, and its scale could be the largest in Japan. Its leaf resembles that of water lily. A yellow flower blossoms at the top of a thin stalk rising above the water, which can be seen from May to November.

Along with Kouhone, rare plants such as Kitagawahirumushiro, Sekishomo, Sadekusa and Nagaemikuri are observed throughout four seasons.

Kitagawa marshland is also called a dragonfly paradise, and more than 40 types of dragonfly have been found there so far.

Especially, a lot of companions of damselfly inhabit, and the typical one is a large by dragonfly. The name of the Army ear sewer was named because the one like the white leaf sticks to four of the male inside foot and hind, and it resembled the winner that referee of the sumo wrestling had. From May to July, we fly around the moor.

In addition, you can routinely observe fish and aquatic organisms designated for endangered species such as Medaka, Loach, catfish, Dytiscidae, Striders, and Ishigame.
