Miyawaki made his professional wrestling debut in Puerto Rico, facing Super Crazy on October 18, 2001. Upon his return to Japan, he joined the Apache Pro-Wrestling Army promotion, where he spent his first years in the business, before making Kaientai Dojo his new home promotion. Miyawaki won his first professional wrestling title on May 6, 2007, when he and Yoshiya defeated Saburo Inematsu and Yuji Hino for the Strongest-K Tag Team Championship. A year later, Miyawaki won the title for the second time with Kazma. Miyawaki has also made several wrestling trips to the United States. In February 2006, he took part in Chikara's 2006 Tag World Grand Prix, where he and Yoshiaki Yago made it to the second round before losing to compatriots Kudo and Mikami. Miyawaki and Yago returned to the promotion the following May to unsuccessfully challenge The Kings of Wrestling for the Chikara Campeonatos de Parejas. In February 2007, Miyawaki took part in Chikara's first-ever King of Trios tournament, where he, Yago and Kudo made it all the way to the finals, before losing to Jigsaw, Mike Quackenbush and Shane Storm. A year later, Miyawaki, Kudo and Susumu made it to the quarterfinals of the 2008 King of Trios tournament, before losing to Eddie Kingston, Joker and Ruckus. The following July, Miyawaki made his debut for Southern California-based Pro Wrestling Guerrilla, teaming with Kazma in a three-way tag team match, where they were defeated by The Young Bucks. On November 20, 2008, Miyawaki made his debut for Osaka Pro Wrestling as the masked character Orochi. He initially joined the rudo army, but in 2010 turned on the group and joined a new stable named Joker, 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. 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. 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. 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. Initially, Miyawaki refused the title, but the Kaientai Dojo commission recognized him as the official champion on June 25. He lost the title to Kengo Mashimo in his second defense on August 24.
