Abstract (in Japanese) (See Japanese page) 
(in English) In basketball, the number of plays involved by each player (points, shots, etc.) is recorded as box scores. In addition,
at the professional level, the units of plays (points, changes in ball possession) may be recorded and published. However, simple
statistics (stats) such as the total number of goals scored do not take into account the circumstances of the game (opponent,
score difference, remaining time, etc.), and these simple metrics may not be able to correctly judge whether a player really
played for the winning of his team. Impact metrics aim to show the contribution of a player to his team’s winning or losing
with a single indicator. An impact metric based on the real-time probability of winning a game has been proposed. The
calculation of this impact metric, however, has been performed for the NBA, a professional basketball league in the U.S. It has
not been for the B.LEAGUE (B League), a professional basketball league in Japan. The purpose of this study is to propose an
impact metric using real-time win probability for the B-League, especially for the B1 players.
