The aim of this study is to analyze how accidents occur during recess under school management quantitatively with accidents data recorded by Japan Sports Council. In total, 823 accidents data in elementary school from 2005 to 2019 were analyzed by principal component analysis, which extracted five components for interpretation (destruction of glass, eye injury in ball game, being off balance, fall from a bar, and game of tag). Multiple regression analysis revealed the factors (age, sex, type of recess, and place of occurrence) that can affect the component scores on each dimension. Specifically, school grade affected scores of 1st and 2nd component score. Sex affected 2nd and 4th component score. Type of recess affected 1st and 5th component score. The place of occurrence affected each component score by some places. It is considered that this result represents how often each summarized situation occurs proportionately in each category with controlling confounders. From these analyses, some trends about how accidents under school management were indicated. It can be considered that quantitative analysis is one profitable method to analyze data of occurrence status and to understand the current situation about accidents under school management.
