On November 20, 2008, Miyawaki made his debut for Osaka Pro Wrestling as the masked character Orochi.[12] He initially joined the rudo army, but in 2010 turned on the group and joined a new stable named Joker,[12] as a member of which he went on to become a two-time Osaka Pro Wrestling Tag Team Champion and a one-time Osaka Pro Wrestling Owarai and Independent World Junior Heavyweight Champion.[13][14][15][16] In April 2013, Orochi, along with Joker stablemates Hayata, Hideyoshi, Kuuga and Masamune left Osaka Pro to join Kuuga's new Doutonbori Entertainment System promotion.[17][18] In June, during the promotion's inaugural event, Miyawaki revealed that he had wrestled under the Orochi mask and made all subsequent appearances for the promotion unmasked and under his original ring name.[19] On June 22, 2014, Miyawaki defeated Saburo Inematsu to win Kaientai Dojo's top singles title, the Strongest-K Championship, after Inematsu legitimately dislocated his left shoulder and was unable to continue the match.[20] Initially, Miyawaki refused the title, but the Kaientai Dojo commission recognized him as the official champion on June 25.[21] He lost the title to Kengo Mashimo in his second defense on August 24.[22]
