The Fukuhaku-kai (福博会) is a yakuza organization based in Fukuoka on the Kyushu island of Japan. The Fukuhaku-kai is a designated yakuza group with an estimated membership of 280 (and up to 360), and has its offices in three other prefectures as well as its headquarters in Hakata, Fukuoka.
The Fukuhaku-kai is one of the five independent designated yakuza syndicates based in Fukuoka Prefecture, along with the Kudo-kai, the Taishu-kai, the Dojin-kai and the Kyushu Seido-kai. These northern-Kyushu based organizations, excluding the Kyushu Seido-kai, have formed an anti-Yamaguchi-gumi fraternal federation known as the Yonsha-kai. The Fukuhaku-kai has never been a member of this federation, however has caused at least one conflict with the Yamaguchi-gumi, which involved firearms, in 2004.
The Fukuhaku-kai has been in conflict with four different Yamaguchi-affiliates over the concessions of Nakasu, the largest red-light district in Kyushu, and also with the Dojin-kai and Kudo-kai over their attempts to enter the same territory.
