The Kudo-kai (工藤會, Kudō-kai) is a yakuza group headquartered in Kitakyushu, Fukuoka on the Kyushu island of Japan,[2] with an estimated 200 active members.

The Kudo-kai is a member of an anti-Yamaguchi fraternal federation, the Yonsha-kai, with three other northern-Kyushu based organizations, the Taishu-kai, Dojin-kai, and Kumamoto-kai.

[11] His funeral was held on July 6 of that year, where the attendees included many yakuza magnates from all over the country, such as those from the Sumiyoshi-kai, Inagawa-kai, Soai-kai, Matsuba-kai, Kyokuto-kai, Aizukotetsu-kai, Sakaume-gumi, Azuma-gumi, Asano-gumi, Kyodo-kai, Goda-ikka, Shinwa-kai, Kyosei-kai, Kozakura-ikka, Kyokuryu-kai, Okinawa Kyokuryu-kai, and even Kiyoshi Takayama of the Yamaguchi-gumi,[8] and possibly some Russian or Italian or Mexican yakuza magnates.

[19] According to a Wall Street Journal article appearing February 2, 2012: "Like many Japanese gangs, the Kudokai even maintains its own public headquarters, the Kudokai Hall — a four-story, fortress-like white building surrounded by tall walls, barbed wire and security cameras — that sits in the center of Kitakyushu, a city of one million residents."
