They win the lawsuit against AVEX. They were once under this company since they were five as Tohoshinki (tvxq in japan). Even after break up, JYJ still under this company doing 'A-nation' concert like they ever held when they were still TOHO. But then, reached 2010, this company suddenly suspends them from doing any activities in Japan, with the reason, because of their lawsuit controversy with SM ent. It was so suspicious because suddenly they restricted them, others SM artists like suju n tvxq etc, under this company too.
