The aim of our investigation was to clarify the achievement situation and features regarding the experiences and results of players who take active parts in the highest ranked football leagues in Japan, Europe, and South American countries.<BR> The average age of players in J-League changed, showing an upward trend, and recorded a peak in the 2014 season (26.85 years), and was higher by 3.80 years than that of Dutch league, which had the lowest value. And in the generation category, the age composition ratio of J-League players showed the lowest values: U 17 (0.57%), U 20 (9.28%) and U 23 (15.34%). And regarding the appearance fraction ratio by age, J-League players also showed the lowest values: U 17 (0.02%), U 20 (3.43%) and U 23 (14.01%). Their U 30 value (78.94%) was near the lowest value－that of Italian league, and their O 31 value (21.06%) was next to the peak－that of Italian league.<BR> In other words, J-League showed lower levels of achievement by young players and a higher average age, in comparison to the leagues in other countries.<BR> One of the factor became clear was that the player production fostered by the "Japan Original System," in which players become professionals after playing at university, is an increasing tendency. Furthermore, other countries such as Germany value the appearance chances of the young generation players and strengthen the upbringing of young players in their own leagues. Thus Japanese players’ experience is behind the age schedule in comparison to other countries and this is having an influence on the clubs and the league, and on competitions with other Asian area teams, and on international matches.
