Biography: Before formally joining Kenji Tanamura's KT-Club stable to pursue a professional career in MMA, Harumi Sakai trained in amateur wrestling, karate, and swimming; excelling in all three at the high school and college level. Unable to ascend to the world ranks of all three sports simultaneously, Sakai chose to combine his natural athletics and combat training towards the booming sport of Mixed Martial Arts.
After assuming a modest 3-1 record, Sakai made his pro-wrestling debut for Tanamura's "FIGHTING UNION.jp" promotion, where he defeated Yuichi Miwa. The group would be short lived however, as Tanamura returned to the MMA ring for the OLYMPUS-FS organization. Sakai naturally followed, where he incurred a 2-3 record. Sakai would return to pro-wrestling shortly after losing his final MMA fight.
Wandering independents with other KT-Club members; along with training at Tanamura's school in Hyogo, Sakai would eventually join KJPW in early 2013. While rough around the edges, and prone to mistakes, he is a very exciting fighter with an equally dynamic personality.
