This study aimed to reveal the transition of the motor ability of schoolchildren from Forest Kindergarten, Japan. In total, 162 children who had graduated from Forest Kindergarten were asked to answer a questionnaire about their motor ability. The results indicated that first - to second - year students had higher levels of motor ability than the national average. Third - to fifth - year students had ordinary levels of motor ability. A tendency for the level of motor ability to decline was revealed. This conclusion contradicts the hypothesis that Kuhara et al. (2015) have proposed. However the present study can be considered more reliability than that of Kuhara et al. (2015), because it had more than three times the sample size.
