Hisayuki Machii

Hisayuki Machii (町井 久之, Machii Hisayuki^?, 1923 - September 14, 2002), nicknamed the "Ginza Tiger" (銀座の虎, Ginza-no-Tora^?), was the founder of one of Japan's most notorious yakuza gangs, the Tosei-Kai.

A Korean, Machii was born Jeong Geon-Yeong (정건영/鄭 建永) in 1923 when Korea was under Japanese occupation. After World War II, Machii settled in Tokyo and became involved in postwar Japan's thriving black market. By 1948, he had formed his own gang, the Tosei-kai or "Voice of the East Gang" which grew to over 1,500 members by the early 1960s. The Tosei-kai became so powerful in Tokyo that they were known as the Ginza police, and even the Yamaguchi-gumi's Taoka had to cut a deal with Machii to allow that group to operate in Tokyo.

Like fellow Yakuza powerbroker Yoshio Kodama, Machii had good relations with the US occupation authorities due to his staunch anti-Communist stance: Tosei-kai soldiers were often used as strikebreakers during the occupation years. Machii himself worked with the United States Counter Intelligence Corps. While leaders of the Japanese yakuza were imprisoned or under close scrutiny by the American occupying forces, the Korean yakuza were free to take over the lucrative black markets. But rather than trying to rival the Japanese godfathers, Machii made alliances with them, and throughout his career, he remained close to both Kodama and Taoka.
