Toa-kai
The is a yakuza syndicate based in Tokyo with a predominantly Zainichi Korean membership. Originally named the , with its historic leader Hisayuki Machii, the Toa-kai was deeply involved in the history of Tokyo's South Korean community and Japan's anti-communist circles in the 20th century. History. The group was formed by Hisayuki Machii, a Zainichi Korean mob boss, as the Tosei-kai in 1948. The Tosei-kai was originally a reported far-right organization of anti-communist activism led by Machii as a sympathizer of Kanji Ishiwara, which was in conflict with the North Korea -associated General Association of Korean Residents in Japan. The Tosei-kai quickly became one of Tokyo's most powerful gangs, and had significantly expanded during the time of the post-war economic growth. Membership reached 1,500 in the 1960s. As the leader of the syndicate, Machii became an essential "fixer" between Japan and South Korea. Increasing police crackdowns by 1965 forced Machii to disband the Tosei-kai and establish a new gang, the , or "East Asia Friendship Enterprise Association". He also formed a "legitimate" company called the , or East Asia Enterprises Company, and named power-broker Yoshio Kodama as chairman  of the board. Afterwards, the Toa Yuai Jigyo Kumiai changed the name as and Toa-kai. The founder Machii retired in the 1980s, and died of heart failure on September 14, 2002, in Tokyo. Also known as a successful businessman, he was 79. Condition. The Toa-kai is a member of a bakuto fraternal federation named the Kanto Hatsuka-kai, along with four other Kanto-based yakuza syndicates, the Sumiyoshi-kai, the Inagawa-kai, the Matsuba-kai, and the Soai-kai. The Toa-kai has aligned itself with the largest known Yamaguchi-gumi syndicate since the syndicate's Taoka era  in the 20th century, and has been closely supported by Shinobu Tsukasa, the sixth-generation godfather of the Yamaguchi-gumi, since 2005 when the sixth era of the Yamaguchi-gumi officially started. Territories. The Toa-kai has its headquarters in Ginza, Tokyo ever since its formation. The Toa-kai has its five branch organizations in Tokyo, and one branch organization outside of Tokyo. Okinawa. The Toa-kai's notable branch organizations include the . The Yoshimi-kogyo is the Toa-kai's only branch organization based outside of Tokyo. Based on the Okinawa island, the Yoshimi-kogyo is one of the  three major yakuza groups in the Okinawa region, along with the Kyokuryu-kai and the Okinawa Kyokuryu-kai. The origin of the Yoshimi-kogyo reportedly traces back to the late 20th century, when Toshio Gibo, an ethnic Okinawan mobster, formed an anti-left nationalist organization named the Makoto-kai in Okinawa under influence of Yoshio Kodama. Gibo met with Machii through Kodama, founding an affiliate of the Tosei-kai in Okinawa. Okinawa's underworld has been known for its exclusiveness since the 20th century, where the dominating Kyokuryu-kai has persistently attacked and violently expelled any yakuza syndicate attempting to  enter the island. The reason why the Toa-kai has been able to be active on the island may be because the group has historically been more oriented to legitimate businesses, and of its gentle stance, in contrast to other yakuza syndicates which have attempted to expand their influences into Okinawa with heavy violence, such as the Yamaguchi-gumi and especially the Dojin-kai. For example, in 2002 in Okinawa, only one Yoshimi member was arrested, while 56 Kyokuryu-kai members and 95 Okinawa Kyokuryu-kai members were arrested.
