A six-month report meeting was held in Tomisato City, Chiba Prefecture, which has been introducing "tag" at nursery schools and kindergartens since last year. The city introduced the game to help children improve their physical strength, as children had fewer opportunities to play outside during the coronavirus pandemic.
The average 25-meter dash time of 4-year-old children was measured in May of last year and six months later in November, and compared with the national average, the boys were about the same.
