The purpose of this paper is to investigate the correlation between physical strength and academic performance in Japanese elementary school children while simultaneously obtaining basic data on physical strength and academic performance. Statistically significant correlations were found between various fitness scores and various academic scores with 5th and 6th grade elementary school boys. The correlations were seen between standing jump test scores, side step test scores, as well as sit-up test scores and many academic scores with 5th grade elementary school girls. With 6th grade girls, the correlations were seen between side step test scores, multi-stage fitness as well as flexibility test scores and various academic scores. These results indicate that correlations exist between physical strength and academic performance. However, it appears to be weak.
