Riichi Yokomitsu left Waseda University without graduating.
Riichi Yokomitsu began publishing in dojinshi such as Machi ("Street") and To ("Tower") after entering Waseda University in 1916. In 1923, he published Nichirin ("The Sun"), Hae ("A Fly") and more in the magazine Bungeishunju, which made his name popular. The following year Riichi Yokomitsu started the magazine Bungei-Jidai with Yasunari Kawabata and others. He and others involved in Bungei-Jidai were known collectively as the Shinkankakuha, or the New Sensation School, with a particular interest in sensation and scientific objectivity.
