Kengo Mashimo is a Japanese professional wrestler currently working for Kaientai Dojo. His style is a combination submission wrestling and hard, martial art strikes. He is currently the ace of Kaientai Dojo.
Kengo Mashimo debuted in Puerto Rico in 2001 as one of the first Kaientai Dojo students. Once Kaientai Dojo arrived in Japan in April 2002, Mashimo started as a wrestler using a grappling and shoot style, finishing his opponents quickly by KO or TKO before starting a short series of matches with Isami which Mashimo lost 3-1, but in doing so, won a lot of crowd support for his fire and spirit. Mashimo did not affiliate with any units in the early years, instead choosing to fight anyone. 2003 also saw Mashimo have his biggest match in his career since debuting as a wrestler, taking on NJPW junior legend Jushin Thunder Liger in an impressive match which opened eyes to him. He also travelled to some other promotions that year, including Riki Chōshū's World Japan. In 2004, he allied with Kunio Toshima and SUPER-X but never officially making a faction. Toshima & Mashimo won the UWA and UWF Intercontinental tag team titles, but vacated them after winning due to winning them in a Handicap match in the tournament final as Hi69's partner, MIYAWAKI was injured earlier in the night. Mashimo also got the biggest chance of his career, challenging Heat for the IWGP Junior Heavyweight Championship. He also made it to the STRONGEST-K '04 finals that year after dispatching of Taka Michinoku in the semi finals. However, Mashimo was defeated by Hi69 in the finals at Tokyo's Korakuen Hall.
In 2005, under the guidance of former Far East Connection manager, 296, Kengo Mashimo formed a stable along with KAZMA called Kinnoutou and Kinnoutou started to dominate, eventually taking in Ryota Chikuzen and Kunio Toshima as well. Mashimo and KAZMA though were the most successful of the group, Mashimo going undefeated from the formation of Kinnoutou and did not drop a fall until well after he left the group. Kengo Mashimo and KAZMA won the first STRONGEST-K Tag Team tournament and were crowned the first ever STRONGEST-K Tag Team champions, the two dominating the tag team scene in K-DOJO as they also won the UWA and UWF Intercontinental Tag Team titles, absorbing them into the STRONGEST-K Tag Team title. When K-DOJO split its roster into two, Mashimo, along with the rest of his Kinnoutou allies were drafted to GET. Mashimo's singles dominance was also highlighted with winning the STRONGEST-K '05 tournament, defeating Yuji Hino in one of the longest singles matches in K-DOJO history.
Early 2006 saw Mashimo and KAZMA lose their first ever tag match together, losing the STRONGEST-K Tag Team titles in February to Makoto Oishi and Shiori Asahi. After losing, signs of friction started to grow in Kinnoutou with Kunio Toshima's sense of justice saving TAKU Michinoku from a Kinnoutou attack. Mashimo and Toshima battled each other until Mashimo defeated Toshima in April. Mashimo resumed his quest to become the ace of K-DOJO and became the first man to win the STRONGEST-K tournament twice by defeating Saburo Inematsu in the final and after his win, he left Kinnoutou and jumped to RAVE where he was a lone wolf after rejecting attempts from New Standard, Kashiwa Gumi and the Boso Heroes. Finally, after two years of chasing, Mashimo finally gained K-DOJO's Strongest-K Championship title by defeating the popular JOE and became the ace of the company. After joining RAVE and winning the CHAMPION OF STRONGEST-K, Mashimo started a rival partnership with the newly unmasked Madoka. Mashimo also appeared regularly on Big Mouth Loud and later Uwai Station shows.
Mashimo and Madoka fought for Mashimo's title at the January Korakuen show, but resumed their partnership after, the two winning the 2007 STRONGEST-K Tag Team Tournament and followed it by winning in the GPWA sponsored Differ Cup tournament. Mashimo's Kinnoutou past was brought back to him, defeating his ex-partner KAZMA in the main event for the 5th Anniversary show in April, then taking on Ryota Chikuzen for his title a few months later. Once GET and RAVE merged, Mashimo kept his partnership with Madoka and brought Boso Boy Raito into their alliance, however never officially becoming a group. Mashimo began a short feud with TAKA Michinoku, Mashimo forcing TAKA to prove himself after an average two years, which lead to a title match on TAKA's 15 Anniversary show which Mashimo won. 2007 has also seen Mashimo start an interpromotional rivalry with BJW heavyweight Daisuke Sekimoto, the two fighting on nearly every Indy Summit show, culmulating in a BJW Tag Team title match with Mashimo teaming with DDT star HARASHIMA in a 30-minute draw against champions Sekimoto and Pro Wrestling ZERO1-MAX's Yoshihito Sasaki.
On September 7, 2012, Mashimo began working for New Japan Pro Wrestling, joining the Suzuki-gun stable, which also included his trainer Taka Michinoku. Mashimo's first big match in New Japan took place on September 23 at Destruction, where he was defeated by Togi Makabe in a singles match. On November 15, Mashimo entered a tournament to determine the inaugural NEVER Openweight Champion. After wins over Bushi and Ryusuke Taguchi, Mashimo was eliminated from the tournament in the semifinals on November 19 by Karl Anderson. From November 20 to December 1, Mashimo took part in the round-robin portion of the 2012 World Tag League, alongside Suzuki-gun leader Minoru Suzuki. The team finished with a record of three wins and three losses, failing to advance from their block. In February 2013, Mashimo took part in Suzuki-gun's war with the Chaos stable, which built to a singles match on February 10 at The New Beginning, where he was defeated by Shinsuke Nakamura.
