|debut = August 21, 1981 of AJPW, along with Kenta Kobashi, Toshiaki Kawada, and Akira Taue; the quartet's matches and ring-psychology would become the basis of the ōdō (), or King's Road style of wrestling.
Debuting in 1981, Misawa became the second wrestler to assume the Tiger Mask persona, which he maintained until the end of the decade. After the departure of Genichiro Tenryu and his exodus, Misawa unmasked in May 1990 and began a rivalry with company ace Jumbo Tsuruta. At the behest of company president Giant Baba, Misawa would lead a team of young talents known as the , which saw many different variants throughout the 1990s, mainly involving Misawa and Kobashi. Following Misawa's victory over Tsuruta on June 8, 1990, AJPW sold out every Tokyo event they held into early 1996, Misawa then led a mass exodus of the promotion's talent to form Pro Wrestling Noah, which was successful in the first half of the decade; as business declined and top star Kobashi temporarily retired in 2006 due to kidney cancer, Misawa continued to work a full-time schedule despite mounting injuries for the company's survival. He sought to mentor Naomichi Marufuji, Takashi Sugiura, and Go Shiozaki to be flagbearers for the promotion in spite of his age. On June 13, 2009, during a tag team match in Hiroshima with Shiozaki against Akitoshi Saito and Bison Smith, Misawa died after a backdrop suplex from Saito, and his death was attributed to the numerous injuries he had accrued for years before his death.
Misawa is regarded by some as the greatest professional wrestler of all time, though the physical demands and consequences of the style in which he worked and the circumstances of his death have made his legacy (or at least that of ōdō) somewhat problematic. Misawa was an eight-time world champion and eight-time world tag team champion, having won the Triple Crown Heavyweight Championship five times and the GHC Heavyweight Championship (which he was the inaugural holder of) three times. Fifty-three of the sixty-nine events at the Nippon Budokan that Misawa headlined were sellouts, Despite never working in the United States during the 1990s, Misawa had a significant influence upon independent wrestling through the popularity of his work among tape-traders in predominantly English-speaking countries.
Misawa was named Wrestler of the Year by the Wrestling Observer Newsletter (WON) on three occasions (1995, 1997 and 1999), and at the time of his death held the record for most WON five star matches, with 25, including one as Tiger Mask. Several of his matches have been dubbed some of the greatest of all time, including his match with Kawada on June 3, 1994, his match with Kenta Kobashi on March 1, 2003, and his and Kobashi's tag team match against Kawada and Taue (the Holy Demon Army) on June 9, 1995.
