Habitat of This Animal:
A:Forest along the valley - A3:Deep forest

Along the mountain valleys grows a high humidity forest. In such an environment, Quercus miyagii, a species of oak often grows in clusters. Some of these grow more than 20m tall and with trunk diameters exceeding 1m, with largely developed buttress roots. Also, there are many animals and plants preferring humid environments, supporting the abundant biota of Tokunoshima Island together with the forest along mountain ridges.
