This research aimed to clarify whether the International Judo Federation Refereeing Rules 2014-2016 (New-IJF Rules) facilitated dynamic judo in the All-Japan Judo Championships (AJJC). Therefore, Kodokan Judo Refereeing Rules` tournaments (KDK Rules` tournaments), International Judo Federation Refereeing Rules` tournaments (IJF Rules` tournaments), and New-IJF Rules` tournaments were compared. The following results were obtained. Regarding winning contents, in the New-IJF Rules` tournaments wins by ippon significantly increased whereas wins by superior performance significantly decreased when compared to KDK Rules` tournaments. Furthermore, for winning methods, points from techniques significantly increased but judges` decisions significantly decreased in the New-IJF Rules` tournaments when compared to KDK Rules` tournaments. However, concerning total points, the results did not show significant differences. As a result, this research confirmed that the New-IJF Rules increased the wins by ippon and points from techniques in relation to winning methods, and decreased the superior performance and judges` decisions in the AJJC. These findings suggest that the New-IJF Rules facilitated dynamic judo in the AJJC.
