TheJapanese national team, which has won the first and second editions of theAmerican Football World Cup and was runner-up, finishing second to the American team, in the 2007 installment of the tournament, was made up almost entirely of players from this league.

Americans are often recruited to play for X League teams, with a strict rule of three per team. No more than two foreign players per team are allowed on the field of play at a time.

The league is split into 4 tiers: X1 Super, X1 Area, X2 and X3.
