The Reality of Galapagosization: The Current State of Coach Changes in Japan's National Team and J-League

Japan's National Team and J-League showing galapagosization with fewer new coach entries. Five teams-浦和レッズ, 横浜F・マリノス, 京都サンガF.C., ガンバ大阪, セレッソ大阪-have switched coaches in J1 League. There are plans for 12 teams by 2025. However, new entries are few, despite the post-WC season. Fans expect new winds, but are left wanting. Notable cases are cross-league transfers, such as 曺貴裁's case from 京都 to 浦和. Also, Ricardo Rodriguez, who has previously managed 大分トリニータ, FC町田ゼルビア, FC東京, セレッソ大阪, 鹿島アントラーズ, and will manage パーボルソルソナマス in 2025. The opening game of this season saw 11 out of 20 J1 teams playing in a 5-4-1 formation, which is the result of this phenomenon.
