Initially, Nakahara favored poetry in the Japanese traditional tanka format, but he was later (in his teens) attracted to the modern free verse styles advocated by Dadaist poet Takahashi Shinkichi and by Tominaga Tarō. After he moved to Tokyo, he met Kawakami Tetsutaro and Shōhei Ōoka, with whom he began publishing a poetry journal, Hakuchigun (Group of Idiots). He was befriended by the influential literary critic Kobayashi Hideo, who introduced him to the French symbolist poets Arthur Rimbaud and Paul Verlaine, whose poems he translated into Japanese. The influence of Rimbaud went beyond just his poetry, and Nakahara came to be known for his "bohemian" lifestyle.
