Hashimoto enrolled in Animal Hamaguchi's professional wrestling dojo while still in high school at the age of 18 in 2008, and eventually graduated from the school in 2009. Hashimoto then joined Big Japan Pro Wrestling's dojo for further training before making his debut on September 21, wrestling Takumi Tsukamoto to a time limit draw. Only a few months into his career, Hashimoto won Kaientai Dojo (K-Dojo)'s 2010 K-Metal League, defeating Ganko Taketo in the final.[2] This earned him a match for the Independent Junior Heavyweight Championship, where he unsuccessfully challenged Marines Mask on June 20, 2010.[3] Hashimoto competed primarily in BJW for the next few years of his career, whilst also making occasional appearances for All Japan Pro Wrestling (AJPW) and Pro Wrestling Zero1 (Zero1). While in Zero1, Hashimoto began teaming with Daichi Hashimoto, dubbing themselves "Team Yamato". Though they share the same surname, they are not related in any way. In late 2012, Team Yamato took part in the Big Japan Tag League, finishing with 4 points and failing to advance to the final.
In early 2016, Hashimoto took part in AJPW's Junior Battle of Glory, but was forced to pull out after suffering an arm injury. Hashimoto spent five months recovering from the injury, and eventually returned to the ring on August 23, 2016,[8] having lost 16 kilograms and looking in better shape than he did prior to his injury.
