Globalization has made Japanese footballers, especially from the J.League, desirable assets for European clubs, highlighting Japan’s rising reputation for developing skilled young talents. Although more Japanese players are moving from J.League to European clubs, Japanese clubs receive comparatively lower transfer fees and related income than clubs in nations with similar FIFA rankings. This study confirms, through data analysis, that the income received by Japanese clubs is indeed significantly lower than that of comparable countries. Furthermore, it reveals that this discrepancy is likely due to the specific negotiation channels and tactics employed by Japanese clubs, particularly their overreliance on players’ agents.
