Kenta Kobayashi (小林 健太, Kobayashi Kenta, born March 12, 1981),^[1] known mononymously as Kenta (stylised in all caps), is a Japanese professional wrestler. He currently works for New Japan Pro-Wrestling (NJPW), where he is a member of the Bullet Club stable. A former amateur kickboxer, Kobayashi's wrestling style is based upon strong kicks and strikes. Kobayashi pioneered both the Go 2 Sleep and Busaiku Knee kick finishing manoeuvres, later popularized by CM Punk and Bryan Danielson, respectively.

Kobayashi started his career in All Japan Pro Wrestling (AJPW), before moving to Pro Wrestling Noah; through Noah's involvement in the Global Professional Wrestling Alliance (GPWA), a global organization of cooperative promotions that allow their competitors to travel abroad to other companies, he has wrestled extensively in American promotion Ring of Honor (ROH).^[7] In Noah, he was a one-time GHC Heavyweight Champion, three-time GHC Junior Heavyweight Champion,^[8] three-time GHC Junior Heavyweight Tag Team Champion, and one-time GHC Tag Team Champion. He was also the winner of the 2012 Global League and the 2013 Global Tag League tournaments.

He is also well known for his tenure in American promotion WWE where he worked under the name Hideo Itami (ヒデオ・イタミ) in the company's developmental territory NXT and later in their cruiserweight exclusive brand 205 Live. In 2019, he departed from WWE, and in May, appeared for NJPW, announcing his participation in that year's G1 Climax and aligned with former tag partner Katsuyori Shibata. He turned on Shibata and joined the Bullet Club, and has since held the Strong Openweight Championship twice and NEVER Openweight Championship and the IWGP United States Heavyweight Championship once each.

Kobayashi was born on March 12, 1981, in Sōka, Japan.^[4] He trained under Kenta Kobashi and Yoshihiro Takayama.^[6]

Prior to wrestling professionally, Kobayashi had a variety of athletic backgrounds, practicing baseball and kickboxing; the latter came to be a strong foundation in his wrestling style often referred to as shoot style.^[2] Kobayashi made his professional wrestling debut on May 24, 2000, against future ally and rival, Naomichi Marufuji, in All Japan Pro Wrestling (AJPW) to compete in their junior heavyweight division. He did not remain in the company long as Mitsuharu Misawa, acting president of AJPW, decided to leave the company following a dispute, leading to Misawa forming his own company, Pro Wrestling Noah.^[9]

One of Misawa's focuses in his new promotion was the junior heavyweight division, which never was treated with high regard in AJPW despite the successes in other promotions. Being sidelined with injuries for the majority of Noah's first year of operation, Kobayashi made his return in July 2001, simply named Kenta.^[9]

Kenta's first involvement in a championship situation came when Naomichi Marufuji was forced to vacate the GHC Junior Heavyweight Championship after suffering a knee injury;^[10] Kenta entered into the tournament held to determine a new champion. He advanced to the finals by defeating Kotaro Suzuki and Tsuyoshi Kikuchi before losing to Yoshinobu Kanemaru on the Navigation with Breeze Tour in June 2002.^[11] Following his relative success in the tournament, Kenta had an increase in his popularity, and he joined his mentor, Kenta Kobashi, in the faction Burning.^[12]

March 1, 2003, saw Kenta team with Naomichi Marufuji for the first time against Makoto Hashi and Yoshinobu Kanemaru in a winning effort. They began teaming regularly as the two entered into a tournament to christen the first GHC Junior Heavyweight Tag Team Champions during the company's Accomplish Our Third Navigation tour; they went to win the tournament by defeating junior heavyweight veterans Jyushin Thunder Liger and Takehiro Murahama in the finals on July 16.^[13] While defending the tag team title, Kenta continued his venture in hopes of winning the GHC Junior Heavyweight title once again on November 30, 2003, in an unsuccessful bid against Takashi Sugiura.^[14]

As part of a reward for the way Kenta performed, he earned himself a trial series of seven matches going into the next year, seeing Kenta able to challenge more established stars in an attempt to elevate his status. Kenta began his trial series on the First Navigation tour, beating Juventud Guerrera. This was followed by defeats to Yoshinari Ogawa and Jun Akiyama. The final match of the series was a loss against Marufuji in October.^[9] While the series was taking place, Kenta and Marufuji continued defending their title against a number of challengers: El Samurai and Ryusuke Taguchi, Yoshinari Ogawa and Kotaro Suzuki, Suzuki and Ricky Marvin, Marvin and Suwa and, on Noah's first Tokyo Dome show, against Kendo Kashin and Takashi Sugiura. Their reign as champions came to an end in June 2005 after almost two years by Kanemaru and Sugiura after the latter pinned Kenta.^[15]

Kenta's first major rivalry in singles competition began in March 2005 following a dispute with SUWA, which led to a series of confrontations between the two, including a violent match that ended in his opponent getting disqualified for assaulting the referee. This led to Kenta getting one more chance to challenge for the Junior Heavyweight title against Yoshinobu Kanemaru at Destiny on July 18, which saw him win the title.^[16] He made his first defense two months later against Suwa, then against Kotaro Suzuki as his alter ego, Mushiking Terry. Simultaneously, Kenta began teaming with Katsuyori Shibata as The Takeover, challenging for the GHC Tag Team Championship, the heavyweight version of the company's tag team title.^[17]

On March 5, 2006, Kenta faced a major challenge in Kenta Kobashi, which saw him lose following a Burning Hammer.^[18] This was followed by a loss of the Junior Heavyweight title on June 4 to Takashi Sugiura. This saw Kenta shift his attention to the GHC Heavyweight Championship, challenging Naomichi Marufuji, losing in a match which won numerous awards and accolades from the wrestling media.^[18]

Kenta spent the majority of his 2007 time in Noah wrestling a variety of tag team and six-man tag team matches with protégé Taiji Ishimori and Akitoshi Saito as partners. He saw most of his success with Ishimori as the two had critically acclaimed matches against a wide variety of competitors, including Ring of Honor (ROH) competitors on loan to the company due to the talent exchange agreement, the Global Professional Wrestling Alliance (GPWA), between ROH and Noah: the Briscoe Brothers, Davey Richards, and Bryan Danielson.^[19] As Kenta and Ishimori progressed as a unit, they entered the first NTV Junior Heavyweight Tag Team Tournament; in the finals they beat Marufuji and Kota Ibushi to win the tournament. They later challenged the GHC Junior Heavyweight Tag Team Champions, Dragon Gate wrestlers BxB Hulk and Shingo Takagi, in a winning effort before losing them to Yoshinobu Kanemaru and Kotaro Suzuki,^[20] only to defeat the team to win the second NTV Junior Heavyweight Tag Team League Tournament.^[21]

Following his loss of the tag title, Kenta returned to competing in singles competition by defeating Bryan Danielson for his second GHC Junior Heavyweight Championship,^[22] which led to a match with Marufuji, who had won the World Junior Heavyweight Championship, to attempt to unify the titles; the match ended in a sixty-minute draw, keeping the titles in the hands of their respective holder, while gaining favorable reviews for their efforts by the media with some claiming it to be a Match of the Year.^[23] Kenta lost the title in February 2009 to rival in their interpromotional rivalry with another member of the GPWA in the Kensuke Office, Katsuhiko Nakajima, only to win it back in the next month.^[24] In October, Kobayashi was forced to vacate the title after suffering a knee injury, which would keep him sidelined for over seven months.^[25]

Kobayashi made his return from injury on June 6, 2010, losing to Naomichi Marufuji in a GHC Junior Heavyweight Championship number one contender's match.^[26] On October 30, 2010, Kenta and Atsushi Aoki defeated Roderick Strong and Eddie Edwards in the finals of a tournament to win the 2010 Nippon TV Cup Junior Heavyweight Tag League.^[27] As a result, Kenta and Aoki received a shot at the GHC Junior Heavyweight Tag Team Championship, but were defeated by the champions, New Japan Pro-Wrestling representatives Koji Kanemoto and Tiger Mask, on November 23, 2010.^[28] On January 29, 2011, Kenta turned heel and join the Disobey stable with members Muhammad Yone, Yoshinobu Kanemaru and Genba Hirayanagi. Kenta would change his look and attitude. Then on March 5, he turned on Yone, removing him from the group. One week later, he renamed the stable No Mercy. On May 25 Kenta and Yoshinobu Kanemaru defeated Atsushi Aoki and Kotaro Suzuki of the ANMU stable to win the vacant GHC Junior Heavyweight Tag Team Championship. After months of trying to persuade his mentor Yoshihiro Takayama to join No Mercy, on June 26 Takayama turned on his partner Takuma Sano during a tag match against Kenta and Kanemaru and became the fourth member of the group. Kenta and Kanemaru would then make it to the finals of the Junior Tag League on July 30. They lost to Atsushi Aoki and Kotaro Suzuki. Then on August 18, 2011, Kenta and Yoshihiro Takayama won the Noah 2 Day Tag Team Tournament. On August 24, Kenta and Kanemaru successfully defended their tag title against Aoki and Suzuki, who got the shot due to their victory in the Junior Tag League. On September 23, Kenta confronted GHC Heavyweight Champion Go Shiozaki after he defeated Takayama to retain the title. Kenta got a number one contender's match with Takashi Sugiura, which he won on October 10. Kenta and Kanemaru lost the GHC Junior Heavyweight tag title to Aoki and Suzuki on October 16.

At Noah's Halloween show on October 31, 2011, Kenta challenged the NJPW team Bad Intentions (Giant Bernard and Karl Anderson) for the GHC Heavyweight Tag Team Championship with Yoshihiro Takayama. The match was set for 2012, but never happened due to injury. In November, Kenta entered Noah's Global Tag League and developed a new submission move he called "Game Over" to help him dispatch heavyweights. Kenta would make it to the finals on November 20, but would lose to Takeshi Morishima. On November 27, he lost to Go Shiozaki in his GHC Heavyweight title shot. In December 2011, Kenta tore his ACL again, forcing him to undergo another surgery to repair it. It was announced that he would be out of action for six to seven months. Tokyo Sports named Kenta the 2011 Technical Wrestler of the Year. Despite his injury, Kenta would stay in Noah and manage No Mercy during his injury. On February 14, 2012, Kenta recruited Shuhei Taniguchi as the fifth member of No Mercy and change his name to Maybach, becoming his mouthpiece and talking for him.

Kenta made his in-ring return on July 22, 2012, losing to Naomichi Marufuji.
