Poet, novelist and critic. In 1901 he self-published his first verse collection, Tsuyujimo, and in 1903 he published the poetry magazine Shirayuri. He gradually developed an interest in novel writing. He discussed the importance of seeking pleasure in each moment in works like the critical essay Shinpiteki Hanju Shugi (Mystical Semi-animalism) (1906). While he became a renowned writer with Tandeki (Indulgence) (1909), he failed in a crab canning business in Sakhalin. Based upon this experience, he published a series of five stories starting from Horo (Wandering) in 1910. He translated Arthur Symons’ The Symbolist Movement in Literature, and in his book Kindai Seikatsu no Kaibo (Anatomy of Modern Life) (1915), he discussed his own unique nationalistic view.
