Tadao Yasuda

In October 2007 he reportedly attempted to commit suicide by carbon monoxide poisoning, using a yeontan. A friend however, interrupted the alleged attempt. He was hospitalized with fears of possible brain damage, but this proved not to be the case and he eventually made a return to wrestling. Speaking to Tokyo Sports Yasuda later denied attempting suicide, saying the poisoning was accidental. On January 11, 2011, Yasuda announced his retirement from professional wrestling. He wrestled his final match on February 4, 2011, in which he was defeated by Genichiro Tenryu.

Though very past his prime physically, Yasuda made his transition to mixed martial arts as a NJPW representative in March 2001. He had his debut at the PRIDE 13 against similarly retired kickboxer and karate champion Masaaki Satake. Yasuda received damage and bled from his face, but he nullified most of Satake' attacks by rushing him through sumo techniques against the ropes every time they were separated. At the end, the unanimous decision was given to Yasuda for controlling the fight.

Yasuda returned to MMA in the K-1 Andy Hug Memorial event, taking on Rene Rooze in a special rules match, but he lost via head kick KO at the third round. He would be more successful in December 2001, when he fought popular K-1 player Jerome Le Banner at an Inoki Bom-Ba-Ye event: Yasuda managed to take him down and submit him by pressing his forearm against Le Banner's throat, getting the biggest win of his MMA career.

Reverting to his real name, he joined the New Japan Pro-Wrestling (NJPW) promotion in June 1993, making his debut in February 1994. Yasuda spent the majority of the 1990s as an undercard wrestler, primarily competing in opening matches or as the fall guy in tag team matches with wrestlers such as Shinya Hashimoto and Kensuke Sasaki, achieving little success. In late 2000, Yasuda, along with Kazuyuki Fujita, became somewhat of a pet project for Antonio Inoki, and both of them were sent to the United States to train in mixed martial arts. Yasuda returned to Japan soon after, and was victorious in his first fight against veteran Masaaki Satake at Pride 13. Yasuda's win helped further legitimise him as a pro wrestler in the eyes of Inoki, and this was rewarded with Yasuda reaching the semi finals of the 2001 G1 Climax, where he lost to Keiji Mutoh. After earning one win and one loss in MMA throughout 2001, Yasuda earned the biggest win of his career in December by choking out veteran Jerome Le Banner. His defeat of Jerome led to Yasuda's stock in New Japan skyrocketing almost overnight, and Yasuda soon found himself elevated from over the hill veteran to top title contender in early 2002. Yasuda earned the biggest win of his pro wrestling career on February 16, defeating Yuji Nagata in a tournament to win the vacant IWGP Heavyweight Championship. Yasuda held the title for 48 days, before dropping it to Nagata in April. In August 2002, Yasuda and Kantaro Hoshino formed their own faction, the Makai Club, a group of wrestlers primarily with MMA backgrounds who worshipped Antonio Inoki like a god. Yasuda was viewed as the leader of the group, and in early 2003 he partnered up with his second in command Kazunari Murakami to enter the IWGP Tag Team Championship #1 Contender Tournament. Despite losing to Jim Steele and Mike Barton in the final, an injury to Steele would give the title to shot to Murakami and Yasuda who unsuccessfully challenged Hiroyoshi Tenzan and Masahiro Chono on February 16. Having retired from MMA, the aging Yasuda's position in the New Japan card began to fall again, and in late 2004 he left the promotion. After leaving New Japan, he started making sporadic appearances for ZERO-ONE and Hustle.

Yasuda's daughter Ayami was born in 1987 and is a model.

He made his professional sumo debut in March 1979 at the age of 15, after leaving junior high school. He was recruited by Kokonoe stable. In 1980 he adopted the shikona of Fujinomori, before switching to Takanofuji in 1984. He first reached sekitori status in March 1985 upon promotion to the second highest jūryō division, but could manage only 4 wins against 11 losses and was demoted back to the unsalaried makushita division. After winning promotion back to jūryō in January 1986 he made his debut in the top makuuchi division only two tournaments later in May 1986.
