Up to the present time, the problem of multi-genres in the written text is rarely taken up on a main theme. This article has taken up works of Haruki Murakami as the writer who is conscious for a genre to consider and has understood a characteristic of the text structure in his "short stories "1st.As a result, the text structure of "short stories "1st which collected his earlier short story works of Haruki Murakami is not a constitution of typical novels. His short stories enumerate some unrelated pieces in a work as topics. They use a text structure to appear a commonality to be underlying in each piece. Such a constitution is the text structure that Naoya Shiga of the modern writer and Kuniko Mukoda as the today's writer have used in an essay work consciously.When he wrote "short stories"1st, Haruki Murakami has states that he had a preparations cycle to a full-length novel from a short story. He calls a work drawn in a viewpoint of the first person according to the lapse of time the realism novel of the "eyes assimilation" model. And he speaks that he has been groping for a different type style from this in a recent interview. From this consideration, this article is able to suppose that the text structure of "short stories"1st is the one that it is like a multi-genre groped for concerning "the history" that Haruki Murakami is going to write in his work group of the latter period.
