[2] The Sakaume-gumi is an old-established, small group that focuses primarily on gambling, and not on other activities like extortion and drugs.

When Japan passed new anti-boryokudan laws in 1992, the Sakaume-gumi was one of the few Kansai-based groups not to launch legal challenges against the new legislation.

The Sakaume-gumi was registered as a designated yakuza group under the Organized Crime Countermeasures Law in May 1993.

[4] One former member of the Sakaume-gumi has achieved a measure of fame in another field: born-again Christianity.

Rev Hiroyuki Suzuki, a tattooed, pinky-missing former Sakaume-gumi gangster, has become an evangelical Christian preacher.
