Designated bōryokudan

[edit]

A designated boryokudan (指定暴力団, Shitei Bōryokudan)[2] is a "particularly harmful" yakuza group[3] registered by the Prefectural Public Safety Commissions under the Organized Crime Countermeasures Law (暴力団対策法, Bōryokudan Taisaku Hō) enacted in 1991.[4]

The numbers that follow the names of bōryokudan groups refer to the group's leadership. For example, Yoshinori Watanabe headed the Yamaguchi-gumi fifth; on his retirement, Shinobu Tsukasa became head of the Yamaguchi-gumi sixth, and "Yamaguchi-gumi VI" is the group's formal name.
