Yoshihiro Tajiri (田尻 義博, Tajiri Yoshihiro?, born September 29, 1970), is a Japanese professional wrestler, perhaps best known for his appearances with Extreme Championship Wrestling and World Wrestling Entertainment. He is currently working in Japan as TAJIRI.
Tajiri had originally wanted to become a kickboxer and trained in kickboxing, but after watching countless wrestling matches from Mexico, he entered the Animal Hamaguchi Wrestling gym and soon won its test match tournament. He debuted professionally in 1994 for Michinoku Pro Wrestling beating Akihiro Yonekawa and also wrestled for Wrestle Association-R. On 16 October 1994 Tajiri made his debut for IWA Japan under his real name. In 1996 he joined Consejo Mundial de Lucha Libre.
In 1996 he left CMLL and joined the hardcore wrestling promotion Big Japan Pro Wrestling in Tokyo. He debuted for BJW under the name Aquarius and beat Unicorn in his first match. On 19 July 1996 he beat Dr. Wagner Jr for the CMLL World Light Heavyweight Championship and lost it to him on 27 July. On July 23, 1997 Tajiri would team up with Ryuji Yamakawa to win the vacant BJW Tag Team Championship and lost it to Gedo and Jado on December 22. The team would regain the titles eleven days later and lose it to Shadow Winger and Shadow WX. He beat Gedo to become the first BJW Junior Heavyweight Champion he would later be stripped of the title when he left the company.
