Rare animals and insects such as pikas, chipmunks, Yezo deer, Daisetsu takane kage, Asahi leopard butterflies, Pale-legged butterflies, and Daisetsu hitori are also inhabiting the mountain, and in 1977 the entire mountain was designated a special natural monument by the government (→Natural Monument).
