A current case unfolding in Japan involving alleged corporate impropriety illustrates the stigma of Yakuza when used as a sort of slanderous tactic. While the businessman in question, Nozoe Kuniaki former CEO of Fujitsu, has seemingly impeccably solid credentials (such as 22 years on the board), alleged links to a supposed Yakuza front company have persisted despite being completely unproven & even said to be based on a rumour. After apparently pissing off a lot of folk during his tenure as CEO, the implication is that Kuniaki is neing "punished" for the actions he took as CEO (decisions which led to over 2000 job redundancies & the selling of certain subsidiaries) after being blackmailed out of his position by fellow board members.
