The purpose of this study is to develop a unit which enables students to experience a fun of reading story. In this study, the researcher developed a class practice of a unit "The Loudest Noise in the World" focusing on three points: 1) to treasure the encounter with works, 2) To make the most of understanding from others, 3) To pay attention to the author's expressions. Through the practice, the results suggest that three points were identified to be effective for the students in enjoying some new interest in reading story such as finding the author's efforts through the expressions and considering what the writer expresses in the story including its title. In addition, students managed to develop their knowledge of reading because of providing the introduction of the unit and the opportunity to discuss the story with other students encouraged students to read the story with an awareness of problem-finding. Concerning the results, the further Japanese classes would be possibly expected to be conducted in order to explore a new fun of reading story.
