Abstract
"NAGARE" is becoming an indispensable discourse in all sports scene, recently. And, it is an important factor to decide the winner. Sportscasters often use this word to describe the abstract situation of the game. There are many studies that made the game analysis and research about "NAGARE", but there are not many studies that attempted to approach a humanities and social science to the identity of "NAGARE" or the structure of "NAGARE". The present study aims to grasp the methodological structure for the intentional creation of "NAGARE". The target is a leader with the perspective of coaching, and yet a person that can be advanced semantic interpretation of "NAGARE" in the volleyball Game. I was using a semi-structured interview method for Kato Yoichi of the former Japanese national volleyball player. He is currently enrolled as a coach and a player of Tsukuba United SunGAIA. Then, the conversational data was analyzed. To analyze the date the Grounded Theory Approach was used, Merton’s Self-fulfilling Prophecy was used as a framework of date analysis. Result revealed that the methodological structure for the intentional creation of “NAGARE” consists of three concepts; deal prophecy, strategic prophecy, foreshadowing prophecy. These three concepts are closely related. The core category that incorporates the three concepts was named ‘Fluctuation of prophecy for the creation
of "NAGARE"’. Leaders is the absolute donor for player’s prophecy, players are the performer of prophecy. From the standpoint that the leader’s prophecy and the player’s prophecy will not necessarily match, it must be produced the common volleyball dimension between the players and leaders. Therefore, it is we should use the cooperative prophecy toward the intentional creation of "NAGARE". So, we should be focused on the relationship between the leader and players to enable mutual understanding of prophecy.
