Nagata debuted and has worked for NJPW since 1992, where he was recognised as company ace in the early 2000s and is a two-time IWGP Heavyweight Champion, a two-time IWGP Tag Team Champion and a one-time NEVER Openweight Champion in addition to having won the New Japan Cup in 2007 and 2011, the G1 Tag League in 2000 and 2010, and the G1 Climax in 2001.

He was inducted into the Wrestling Observer Newsletter Hall of Fame in 2018.

Amateur wrestling career Before turning professional, Nagata was a successful amateur wrestler. Nagata met future professional wrestling rival Minoru Suzuki in the amateur wrestling circles. In 1986, when they both were seniors, Suzuki beat Nagata first in a Tokyo high school tournament and again at the Japanese sectionals. Competing in the Greco-Roman style, Nagata represented Japan in the Asian Championships twice, placing fifth in 1993 and placing fourth in 1994, in one World Cup at the Espoir level in 1988, and in the 1991 World Championships, placing twenty-first.

Professional wrestling career

New Japan Pro Wrestling (1992–1997) Nagata joined New Japan Pro-Wrestling in April 1992 and trained in the NJPW Dojo. He debuted on September 14 of that year, facing Hiroyoshi Yamamoto. Nagata increased in stature during the 1995 inter-promotional angle pitting NJPW loyalists against UWF International wrestlers. Taught the shoot-style by Kazuo Yamazaki, who had returned to NJPW after leaving UWFI, Nagata learned the style that has been his trademark ever since.

World Championship Wrestling excursion (1997–1998) Nagata joined the American World Championship Wrestling promotion in March 1997 as an arrogant villain. He was managed by Sonny Onoo, who also acted as his translator. On March 3, he lost to Ernest Miller in a dark match. His TV debut match was a lost to Dean Malenko on April 21. He began feuding with Último Dragón, with Nagata repeatedly injuring Dragon's shoulder. The two rivals faced one another at Halloween Havoc on October 26, with Nagata forcing his smaller opponent to submit with an arm submission hold. They faced one another in a rematch at World War 3 on November 23, with the added stipulation that, should Dragon win, he would receive five minutes alone in the ring with the interfering Onoo. Nagata was able to pin Dragon following a distraction by Onoo, thus ending their feud.

In 1998, Nagata teamed with Kensuke Sasaki and entered a tournament for the number one contendership for the WCW World Tag Team Championship. Nagata and Sasaki won the tournament, but the title match never took place. Nagata left WCW in August 1998 and returned to New Japan.

Return to NJPW (1998–present)

Main event run (1998–2010) Upon his return, Nagata began challenging for the IWGP Heavyweight Championship. On September 23, 1998, Nagata fought Scott Norton for the vacant title (the previous champion, Masahiro Chono, had suffered a neck injury) in Yokohama, but was defeated.

On August 28, 1999, in Tokyo, Nagata and Manabu Nakanishi defeated Tatsutoshi Goto and Michiyoshi Ohara for the IWGP Tag Team Championship. They held the title until July 20, 2000, when they lost to Satoshi Kojima and Hiroyoshi Tenzan in Sapporo, Hokkaido. Nagata and Nakanishi feuded with Kojima and Tenzan for several months, but were unable to regain the title. On January 4, 2000, his mentor Kazuo Yamazaki retired and Nagata served as his final opponent, winning the match.

In March 2000, Nagata formed an ill-fated stable known as Fighting Club G-EGGS, with all the stable member having legitimate sporting backgrounds. The stable included Manabu Nakanishi, Nagata's tag team partner and co-IWGP Tag Team Champion at the time, Masakazu Fukuda, Yutaka Yoshie and Brian Johnston. Fukuda died in April 2000 from a brain hemorrhage suffered after he took a taking a flying elbow drop during a match against rookie Katsuyori Shibata, and was honored with a ten-bell salute and a tribute show in September of that year. Johnston's participation in the group was largely limited after he suffered a stroke, and Nagata eventually disbanded G-EGGS on June 16, 2001.

In August 2001, Nagata won the eleventh annual G1 Climax tournament, defeating Keiji Mutoh in the finals by submission. Nagata had entered the tournament twice before, but was eliminated in semi-final matches on both instances. Nagata challenged for the IWGP Heavyweight Championship once again after it was vacated by the injured Kazuyuki Fujita on January 4, 2002, but lost to Tadao Yasuda on February 16, 2002, in a tournament final. Nagata defeated Yasuda for the IWGP Heavyweight Championship on April 5, 2002, in the Nippon Budokan. Immediately following his victory, Nagata was attacked by Pro Wrestling Noah mainstay Yoshihiro Takayama. He held the title for thirteen months (setting a record for most successful title defenses in the process) before losing to Takayama on May 2, 2003, in the Tokyo Dome.

On January 4, 2004, he defeated Kensuke Sasaki after 12 minutes of intense action at the Tokyo Dome. In April 2005, Nagata formed "Team JAPAN", a group of former amateur wrestlers with a grudge against the younger generation of wrestlers in NJPW. On December 11, 2005, Nagata challenged Brock Lesnar for his IWGP 3rd Belt Championship but was defeated.

On June 28, 2006, Nagata was announced as a participant in the 2006 G1 Climax, his eighth appearance in the tournament. Nagata challenged for the Triple Crown Heavyweight Championship at the January 4 Dome Show entitled Wrestle Kingdom in Tokyo Dome against the current Triple Crown champion, Minoru Suzuki. Nagata lost after Suzuki applied the Saka-otoshi. He did not submit, but was knocked-out by the hold.

On March 21, 2007, he won the third annual New Japan Cup, becoming the first man to win both the New Japan Cup and the G1 Climax Tournaments. On April 13, 2007, Nagata defeated Hiroshi Tanahashi to win the IWGP Heavyweight Title, marking his second reign, and the first time he has held the belt since April 2002. On October 8, 2007, Hiroshi Tanahashi beat Yuji Nagata at Tokyo Sumo Hall to win the IWGP title. In January 2008 Yuji faced Kurt Angle for the IGF version of the IWGP Heavyweight Championship and lost by submission.

Nagata returned from an undisclosed injury in the summer of 2008 to lead New Japan against Zero1 as New Japan's ace. Yuji feuded particularly with World Heavyweight Champion Masato Tanaka and on October 13, on a New Japan event, Nagata defeated Tanaka to win the World Heavyweight Title following two Backdrop Drivers. He recently defended the belt successfully against Kohei Sato. Nagata made his V2 title defense on December 16 against Tatsuhito Takaiwa.

Following this victory, it was announced Nagata would defend the belt at the January 4 Dome Show entitled Wrestle Kingdom III. At the event, Nagata again overcame Tanaka to make his third defense of the title in 11:41 after a Backdrop Suplex Hold.

On February 15, Nagata defeated Hirooki Goto at New Japan's ISM tour in a match that was supposed to happen at last year's ISM tour show. Nagata lost the World Heavyweight Title on February 27 to Shinjiro Otani after a Dragon Suplex Hold. The following day, Nagata and Hiroshi Tanahashi would defeat Masahiro Chono and Goto. After the match, Nagata announced his participation in the New Japan Cup and intended on winning so he could challenge the winner of the Tanahashi-Angle IWGP Title match. Nagata would make his way to the semifinals of the tournament, before losing to Hirooki Goto. In the fall of 2009 Nagata formed the stable Seigigun ("Blue Justice Army") with Wataru Inoue, Mitsuhide Hirasawa and Super Strong Machine. Yuji had started mentoring both Inoue & Hirasawa, and Strong Machine was entering the role of head trainer at New Japan's dojo.
