The island consist of two islets - the smaller northern (where highest elevation rocks are located) is or and larger southern is or Kutsujima has been recognised as an Important Bird Area (IBA) by BirdLife International because it supports populations of black-tailed gulls, Japanese murrelets and Swinhoe's storm petrels. Currently, the islets are designated as the Kanmurijima-Kutsujima Wildlife Protection Area, and any landing is prohibited.
According to inscriptions on , the Kanmurijima and Kutsujima are the remains of the much larger island which submerged following an earthquake in 701 A.D. The topography of seafloor seems to support the claim, as the steep 60-meter cliff is located underwater off eastern coast of Kanmurijima and Kutsujuma, indicating a recent crustal fault. The northern islet is inaccessible without rock-climbing equipment, and was the famous hermits prayer location during the late 19th century.
In the Oomoto religion, Kutsujima is considered sacred to the kami Ushitora no Konjin (è®ã®éÂÂç¥Â).
