On hills whose surroundings were dug for soil,a wetland holds seven kinds of insectivorous plants.

Itchoda Wetland lies in hills 30 to 40 m above sea level. The surrounding land was dug as a soil quarry for reclamation in the first half of the Showa 30s (1955-59), changing the terrain sharply; when farmland development came, 11,000 m² including the wetland was designated a protected area. The town writes that seven kinds of insectivorous plants grow there.
