I honestly don't remember where i watched it but there was an interview with someone about the problems within tier 2 and tier 1 Japanese valorant. The tldr was that a lot of these players from JP and KR are young and sign contracts without an agent, lawyer or even parent present so a lot of these players just end up in contract jail for sometimes up to 5 years cuz they don't fully grasp the contract details. There was even a contract a dude signed and didn't read where it stated if he doesn't play for that team anymore he can't compete in the Jap league for 2 years. Thats also why these jap teams in both tiers barely make roster changes or if they do its the same recycling of players. Its cuz everyone else is in contract jail with extreme buyouts and conditions.
