Tsuruta participated in many sports, such as swimming, basketball, and sumo, while attending Hikawa Senior High School in Yamanashi-shi, Yamanashi Prefecture.
He also competed in the 1972 Summer Olympics in Munich. He finished the Greco-Roman tournament with no wins.
Professional wrestling career
Scouted by AJPW promoter Giant Baba, he was sent to the local Amarillo, Texas, promotion in the U.S. to train as a pro under Dory Funk Jr. Known as "Tommy Tsuruta", he worked in several major NWA territories including Detroit, St. Louis, and Florida as well as West Texas. He was among the first Japanese wrestlers to be cheered by an American crowd, due to his hard work ethic and wrestling ability. The name "Jumbo" was given to him by a fan contest in Japan to replace his first name, which was seen as too feminine. He defeated Nick Bockwinkel on February 23, 1984, to win the AWA World Heavyweight Championship in Tokyo, Japan. He lost the title to Rick Martel on May 13, 1984, in St. Paul, Minnesota. Tsuruta and Yoshiaki Yatsu became the first World Tag Team Champions on June 10, 1988.
In 1992, he completed the October "Giant Series" tour before disappearing from the company for almost a year due to Hepatitis C.[2] For the rest of his career, he participated mostly in comedic (i.e. exhibition) six-man tag team matches; he frequently teamed with Baba and old rival Rusher Kimura in matches against teams which included Masanobu Fuchi, Haruka Eigen, and other old-timers. Tsuruta's last match was on September 11, 1998 in a six man tag. He announced his retirement on February 20, 1999, and held a ceremony on March 6, 1999.
Post-retirement and death
Four days after Tsuruta's retirement, he moved with his family to the United States to be a visiting researcher at the University of Portland in Oregon. Tsuruta had a bachelor's degree in political science and earned a master's degree in coaching in 1997, later becoming a part-time instructor in physical training at his old University.
His health deteriorated, however, as he had been diagnosed with Hepatitis B which eventually turned to full blown liver cancer as well as cirrhosis of the liver, and by the end of the year he was back in Japan. Due to strict laws over organ donation in Japan, meaning only relatives with matching blood types can donate, Tsuruta had to try and find a donor elsewhere. In April 2000, he left for Australia in search of a liver donor, and two months later, a donor was found in Manila in the Philippines. Tsuruta underwent surgery on May 13, but during the liver transplant he began bleeding uncontrollably, and died at the National Kidney and Transplant Institute in Quezon City, Philippines on May 13, 2000, from complications of the liver transplant at the age of 49.
