In order for Japan’s volleyball to develop tactically, it is important to analyze teams on a worldwide level, though it is also vital to look domestically. ‘Attacks’ are considered to have a significant impact on the outcome of a match. Using the V-League (2019-2020 season), which is the top league within Japan, as the subject, I have analyzed the correlation between ‘attacks’ and the outcome of a game. The purpose of this study was to obtain guidelines to create better teams, etc. by subdividing the attack (apart from the situational aspect) and analyzing each data set. The results showed that using the Middle on a good pass, its kill percentage and error percentage, as well as the right-side player, known as the Opposite, has a significant impact on the result of a game. The team that uses their middle effectively on a good pass and has an opposite that can put the ball away even on a broken play wins. This study was very meaningful as it clarified the structure of volleyball within Japan. Most of the foreign athletes within the V-League are Opposites, and it is reasonable to state that the foreign athlete’s ability determines the outcome of a team. Based on this research, it is necessary to come up with a structure that not only wins games domestically, but on an international level as well.
