 note = {This study aims to analyze, via official data and released videos, the global tendency of the attack and defense tactics of water polo games and the performance of Japan’s team during the Olympic Games Tokyo 2020.
The results were as follows.
1）European strong teams, which are Serbia, Greece, Hungary, and Spain, monopolized a high rank by strengthening their style of leading exclusion fouls from the opponents at the center position.
2）The new rules promoted speedy attacks until 2019, but did not produce new change at the Olympic Games.
3）Most teams entered one goalkeeper and eleven field players as members in each game.
4）The Japanese team must further raise the shot accuracy although offensive ability increased, and it must raise the defense ability of extra man and middle-distance shots.},
