Crime · Japan
Bōryokudan
In plain English
The statutory category for an organised crime group in Japan. The governing act defines it as an organisation likely to facilitate its members in collectively or habitually committing illegal acts of violence. It is the term that appears in law, in police statistics and in court, and it is not interchangeable with the word most English readers know.
Register
Legal term. Defined by statute. Carries legal consequences.
The instrument
暴力団員による不当な行為の防止等に関する法律
Act on Prevention of Unjust Acts by Bōryokudan Members
Act No. 77 of 1991; in force March 1992
Commonly abbreviated 暴力団対策法 or 暴対法 (Bōtaihō).
Literally
Violence group — 暴力 violence, 団 group or body.
What English gets wrong
Treating 暴力団 and やくざ as the same word. One is a statutory category with legal consequences attached; the other is vernacular with none. In a compliance file or an analytical product the difference is the whole point.
What to write instead
bōryokudan on first use with a gloss, then bōryokudan. Where matching an agency register matters, note that the NPA's own English is split between "Boryokudan" and "organized crime groups".
The issuing body's own English. The NPA's standing English pages render it "Boryokudan", untranslated, glossed as commonly referred to as yakuza. Usage is not uniform: its most recent English White Paper digest uses "organized crime groups" in running prose and does not use "Boryokudan" at all. Do not claim the NPA always renders it one way.
