We investigated the ideal way to conduct the Home-Grown-Player (HGP) system. In this study we clarified the number of people enrolled in HGP, the time of participation, the training environment, and the area where participants grew up, to provide basic data for the J-League from the viewpoint of training young players in Japan. We investigated definition 1 (J-HGP1), which is a player who has been in the club for 3 years from age 15 to 21. In addition, J-League also separately defined players who have graduated from high school or university (J-HGP2). We calculated the contrast value of the HGP Ratio Value (HRV) as an indicator of the achievement of training. Also, in order to know the regional nature of HGP, clubs and development organizations were categorized by prefecture (J-HGP2 (prefecture)). The ratio of the number of HGP enrolled persons was 30% or more and the HRV was 1.00 or more. In J-HGP1, C. Osaka (1.33) was the only club in the J-League. This suggests that the young players who have been nurtured are being sent to clubs in Japan and overseas, and that a cycle in which changes in the generations of the players and renewal of their metabolism is emerging. In J-HGP2, the enrollment ratio and participation time ratio values were higher than those of J-HGP1. This indicates that players in the J-League are being brought up in the training environment of high schools and universities. This remarkably represents a characteristic of being a rare league in many worlds. Furthermore, in J-HGP2 (prefecture), there are 9 prefectures where the enrollment ratio exceeded 30%. The HRV of 1.00 or higher were found in the two metropolitan areas of Tokyo (1.12) and Chiba (1.04). It turns out that Japanese HGP is affected by the characteristics of the environment which is made up of many high schools and universities.
