In 2007, Kasumi Ishikawa attended the World Table Tennis Championships in Zagreb on behalf of Japan and marked the youngest-ever talented player of the Japanese table tennis team to show presence in the World Table Tennis Championships. In the same year, Kasumi Ishikawa teamed up with Maharu Yoshimura to win the mixed doubles champion of the World Table Tennis Championships in Selldorf; later, she gradually grew into a top player in the table tennis world and one of the most important opponents of the Chinese table tennis team. In this paper, by collecting the video playback data and other information from authoritative official websites like International Table Tennis Federation, the three-stage index evaluation method is adopted for collecting data for six matches between Kasumi Ishikawa and Chinese elite athletes from 2019 to 2022, and analyzing Kasumi Ishikawa's techniques and tactics to provide data reference for Chinese athletes to fight against Harimoto Tomokazu in the future.
