　In order to increase the national presence of Japanese football, it is necessary to first understand the current prevalence. While it has been said that the prevalence of football varies considerably across the country, it has not been examined objectively. This study aimed to analyze the ratio of the number of football players, teams, and referees of each prefecture to the total population based on data published by the Japan Football Association. 　The total population, the number of football players, teams, referees, and high grade referees differed among each prefecture, and the three prefectures of Akita, Nara, and Wakayama were lower in the ratio of football players and teams to total population than the other prefectures. In addition, the number of teams showed a very high relationship (r=0.91) with the number of players and moderately-high relationships (r=0.70 and 0.73) with the referees. The relationships of the number of referees and high grade referees and of players and the number of both types of referees were moderate(r=0.55-0.68). 　From the present results, the prevalence of football differs among each prefecture and is lowest in the three prefectures of Akita, Nara, and Wakayama. The number of football referees is closely related to the prevalence of football.
