It’s a government act to try cripple the Yakuza, as just a few decades ago they were very public and openly boasted their parallel state status, so Japan tightened their ability to open firms, bank accounts and business.
Yakuza today went back to operating mostly in the shadows, like organized crime usually is in other countries, with the public Yakuza persona having less means to entice aspiring thugs to become members, that’s why disfranchised and independent criminal organizations are on the rise in Japan, no much benefits in becoming a public target for hard government sanctions by being a real yakuza.
