other. This is one of the few times that Yakuza members display their tattoos to others, as they normally keep them concealed in public with long-sleeved and high-necked shirts. When new members join, they are often required to remove their trousers as well and reveal any lower body tattoos. Syndicates Three largest syndicates The Yakuza are still very active, and although Yakuza membership has declined since the implementation of the Anti-Boryokudan Act in 1992, there are still approximately 12,300 active Yakuza members in Japan as of 2021, although it is possible that they are a lot more active than statistics say. The Yakuza does not consist of just one group, rather there are many different syndicate groups that together form one of the largest organized crime groups in the world. Designated bōryokudan A is a "particularly harmful" Yakuza group registered by the Prefectural Public Safety Commissions under the enacted in 1991. Groups are designated as boryokudan if their members take advantage of the gang's influence to do business, are structured to have one leader, and have a large portion of their members hold criminal records. Under the Organized Crime Countermeasures Law, the Prefectural Public Safety Commissions have registered 24 syndicates as the designated boryokudan groups. Fukuoka Prefecture has the largest number of designated boryokudan groups among all of the prefectures, at 5; the Kudo-kai, the Taishu-kai, the Fukuhaku-kai, the Dojin-kai and the Namikawa-kai. After the Organized Crime Countermeasures Law was enacted, many Yakuza syndicates made efforts to restructure to appear more professional and legitimate. Designated boryokudan groups are usually large organizations (mostly formed before World War II, some before the Meiji Restoration of the 19th century); however, there are some exceptions such as the Namikawa-kai, which, with its blatant armed conflicts with the Dojin-kai, was registered only two years after its formation. Current activities Japan Yakuza are regarded as semi-legitimate organizations. For example, immediately after the 1995 Kobe earthquake, the Yamaguchi-gumi, whose headquarters are in Kobe, mobilized itself to provide disaster relief services (including the use of a helicopter), and this was widely reported by the media as a contrast to the much slower response by the Japanese government. The Yakuza repeated their aid after the 2011 Tōhoku earthquake and tsunami, with groups opening their offices to refugees and sending dozens of trucks with supplies to affected areas (see below). For this reason, many Yakuza regard their income and hustle
