The Prince Takamado Cup, since 2018, is divided in two age-restricted tournaments, being them the "Prince Takamado Trophy JFA U-18 Football League" (Japanese: 高円宮杯 JFA U-18サッカーリーグ) and "Prince Takamado Trophy JFA U-15 Japan Football Championship" (Japanese: 高円宮杯 JFA U-15サッカー選手権大会).

Both tournaments are annually-contested and run by the Japan Football Association for the under–18 and under-15 sides.

Currently, in the Prince Takamado U-18 Premier League, 24 teams are split into 2 groups with 12 teams in each, which are called Premier League East, and Premier League West, with each team's geographical positions being the determining factor to decide whether the club should be on the East group, or on the West group.
