Some of the country's first major stars were singer Ichiro Fujiyama and composer Masao Koga. Koga attempted to initiate fusion of Western jazz and Japanese dodoitsu. Fujiyama's 1931 song , composed by Koga, became a major hit in Japan. This song created a fusion of Fujiyama's crooning and Koga's guitar play. Using the vocal technic "Mezza Voce" with a microphone, Fujiyama sang the song by the deep voice of not Opera's G minor but D minor. Fujiyama's song sold 600,000 copies. However, Fujiyama was an elite student, who specialized Western classical music in the Tokyo Music School. "Ryūkōka" songs often dealt with the "Ero Guro Nansensu" things. Since his school regarded "ryūkōka" as bad form at that time, Fujiyama was once suspended from the school, though Fujiyama was not dismissed from the school because Klaus Pringsheim Sr., a professor of the school, opposed the proposal of Fujiyama's expulsion.
