The recent trend of the so-called cultural research by the Japanese contemporary literature research is on the detailed probing in the literature creation or on the writer's background The focus of this paper is to probe into the poet who has an elegant name, ”Takuboku”, and has his premier appearance in the 1903 December edition of the ”Myojo” -Ishikwa Takuboku (1886-1912) Some say name ”Takuboku” as named by the master of the ”Myojo”-and Yosono Tekkan while Iwaki Yukinori believed it was Takuboku whom had given himself of such name. As for me, I would think it was the name under the collaboration of Tekkan and Takuboku. But the question I would like to raise is the meaning of probing into the relationships between the ”composition” and the ”writer” in the research of literature through the discussion of elegant names.
