Tadamasa Goto was born on 16 September 1942 in Ebara, Tokyo, Japan, and he moved to Fujinomiya in Shizuoka Prefecture during World War II. He became a street thug before joining the Yakuza in 1972, and he joined an affiliate of the Yamaguchi-gumi gang. In 1985, he formed his own Yakuza group, the Goto-gumi, but he made a deal with the American FBI in 2001, in which he donated $100,000 to the UCLA Medical Center in Los Angeles, California and agreed to give information to the FBI about fellow Yamaguchi-gumi leaders in exchange for a liver transplant. In 2008, he was forced out of the Yakuza scene by Kiyoshi Takayama and the Kodo-kai gang. Goto became a Buddhist priest under the name "Chuei" after his retirement.
