Kaientai Dojo (2003–2011) Kazma was trained by
Taka Michinoku at his
Kaientai Dojo wrestling school and made his debut for the promotion on 3 May 2003. In 2005, Kazma took on Michinoku for the
Strongest-K Championship and a few days later took part in the Strongest-K 2005 tournament and would lose both. In 2005, under the guidance of former Far East Connection manager, 296, Kazma formed a stable along with
Kengo Mashimo called Kinnoutou and started to dominate, eventually taking on Ryota Chikuzen and Kunio Toshima as well. In March, Kazma defeated
Miyawaki to become the number one contender for the Strongest-K Championship and a month later took on former Kinnotou member Kengo Mashimo for the championship and lost. In the beginning of 2008, Kazma teamed up with Takizawa and lost in the first round of the Kaientai Dojo Tag League 2008. With this loss Kazma teamed up with
Yuji Hino to take part in the same tournament and reached the final before being eliminated by Mashimo and Madoka. After the tournament, Kazma joined the stable OMEGA and for most of the first part of 2008 teamed up with members of OMEGA to take part in tag team matches against rivals Handsome and Slum. Throughout 2009 and 2010 Kazma would defend his championship on multiple occasions and always retaining it until 15 August 2010, where he lost it to Hino. With the loss of his title Monster Plant would disintegrate, leaving Kazma on his own. Sakamoto went on to lose every televised FCW match he participated in, including defeats to
Dean Ambrose and
Mike Dalton. On 26 March 2012, Sakamoto made his first appearance on WWE television in a vignette for the re-debuting
Lord Tensai. Sakamoto made his debut on the 2 April 2012 episode of
Raw as the follower of Tensai. Sakamoto would aid Tensai by interfering in his matches and attacking his adversaries. From June, with Tensai losing more frequently, he would often vent his frustrations by abusing and attacking Sakamoto, who would remain loyal to his master. By September, Tensai stopped appearing with Sakamoto, who disappeared from television. Following his disassociation from Tensai, Sakamoto returned to WWE's developmental territory, the former FCW, which had been rebranded into
NXT; he made his
NXT debut on the 16 January 2013 episode, losing to
Adrian Neville. While facing
Briley Pierce on the 8 May episode of
NXT, both men were attacked by
Conor O'Brian; this led to both men challenging O'Brian to a handicap match during the next episode, which O'Brian won. On 17 May 2013, Sakamoto was released; his last match was a battle royal on the 29 May episode of
NXT (which was
taped before his release) to determine the #1 contender for the
NXT Championship where he and Pierce were the first men eliminated from the match courtesy of
Mason Ryan.
Return to Japan (2013–present) On 11 June 2013, Kazma, billed under the ring name Kazma Sakamoto, returned to Japan at a
Pro Wrestling Zero1 event, where he announced that he would be taking part in the
2013 Fire Festival. On 15 July, Sakamoto wrestled his first match since his WWE release, when he defeated Tank Nagai at a Kaientai Dojo event. Sakamoto finished his Fire Festival on 4 August with a record of two wins, one draw and two losses, failing to advance to the finals of the tournament. On 15 September, Sakamoto made his debut for
Wrestle-1, teaming with
Ryoji Sai in a tag team match, where they defeated
Ryota Hama and
Yasufumi Nakanoue. Sakamoto replaced an injured
Kohei Sato as a member of a heel stable named Desperado, led by
Masayuki Kono, and later in the event helped Kono defeat
Masakatsu Funaki. Back in Kaientai Dojo the following day, Sakamoto and Kengo Mashimo defeated Daigoro Kashiwa and Ricky Fuji to win the Strongest-K Tag Team Championship. They lost the title in their first defense on 10 November to the team of Kaji Tomato and Taka Michinoku. On 11 January 2014, Sakamoto made his debut for
Wrestling New Classic (WNC), defeating
Masaya Takahashi, after which he challenged and attacked
WNC Champion Tajiri. This led to a title match between the two on 30 January, where Tajiri retained his title. Through Wrestle-1's working relationship with American promotion
Total Nonstop Action Wrestling (TNA), Sakamoto worked TNA's
Bound for Glory event in Tokyo on 12 October, losing to
MVP. On 30 January 2015, Sakamoto received his first title shot in Wrestle-1, when he and Desperado's newest member Koji Doi unsuccessfully challenged
Kaz Hayashi and
Shuji Kondo for the
Wrestle-1 Tag Team Championship. On 26 June 2015, it was announced that Sakamoto had signed with Wrestle-1, officially ending his days as a freelancer. Shortly afterwards, Sakamoto became the new leader of Desperado, after kicking Kono out of the group. Under the new leadership, the stable was renamed "Real Desperado" on 13 October. On 3 November, Sakamoto, Koji Doi and
Nosawa Rongai defeated Jackets (
Jiro Kuroshio,
Seiki Yoshioka and
Yasufumi Nakanoue) for the
UWA World Trios Championship. They lost the title back to Jackets on 27 November. On 6 March 2016, Sakamoto and Real Desperado's newest member Yuji Hino defeated Masayuki Kono and Shuji Kondo for the Wrestle-1 Tag Team Championship. They lost the title to Yasufumi Nakanoue and
Yuji Okabayashi on 8 June. On 31 August, Sakamoto's contract with Wrestle-1 expired and he became a freelancer once again. ==Other media==
