Japanese media is reporting that players on the national football team are threatening to boycott international friendlies if they aren't given more money.
The Japan Pro-Footballers Association said the players are not satisfied with the amount they receive for playing in friendlies.
Japan's players receive between $2,000 and $2,500 for every match they win, but are asking the Japan Football Association for a minimum of $12,000.
Tetsuro Kiyooka, executive officer of the JPFA, was quoted by Kyodo News agency as saying "we have no intention of backing down."
JPFA lawyers will hold meetings with lawyers from the JFA on Tuesday to try to resolve the conflict.
