Seiki Yoshioka

Professional wrestling career

Wrestle Gate (2007-2013) A day after starting at university, Yoshioka began training at Wrestle Gate, run by Hanzo, and would train there whilst also attending school. On October 5, 2008, he made his official debut teaming with Susumu in a losing effort against Kindaichi Hogo & Minoru Fujita on Wrestle Gate's 5th Anniversary show. Eventually, he changed his ring name to just Seiki (stylized in all capital letters).

In 2011, Seiki won his first belt, winning the Hakata Tag Team Championship (a championship managed by Pro Wrestling Kageki) with Susumu, in a team known as Scramble☆Time. They successfully defended the belts 3 times before losing them to Hanzo & Victory Shanghai. During this time, when All Japan Pro Wrestling (AJPW), DDT Pro-Wrestling (DDT) & Wrestling New Classic (WNC) were in Hiroshima & Okayama, Seiki would occasionally perform on their shows.

Seiki unsuccessfully challenged for the Hakata Light Heavyweight Championship (held by Cosmo Soldier) twice in 2012 while spending that year wrestling his final matches for Wrestle Gate & Pro Wrestling Kageki.

All Japan Pro-Wrestling (2013, 2019) In April 2013, after finishing his pharmacist degree, Seiki decided to start wrestling full-time in Tokyo and graduate from Wrestle Gate in Hiroshima. He wrestled his farewell match on May 26, 2013, teaming with Betcha Hogo in a winning effort against Daisuke Masaoka & Yuki Tanaka. Sanada said that he had 'changed so much in these two weeks'.

On November 7 on Kassen ~ Battle Zero1vsW-1 Full Battle~ in Shinjuku Face, Yoshioka won Pro Wrestling Zero1 (Zero1)'s NWA International Lightweight Tag Team Championship with Shuji Kondo from Takuya Sugawara and "brother" Yasshi, after Yoshioka pinned Sugawara. After two straight unsuccessful challenges for Minoru Tanaka's Wrestle-1 Cruiser Division Championship, he started teaming with Jiro 'Ikemen' Kushio. This alliance eventually came to include Yasufumi Nakanoue, and the three became known as Jackets, as all three men wore jackets during their matches. They won the UWA World Trios Championship from New Wild Order (Akira, Jun Kasai & Kumagoro) on October 9, 2015, at Wrestle-1 Tour 2015 Fan Appreciation Day in Korakuen Hall. On January 31, Jackets would attempt to regain those belts against Kaz Hayashi, Minoru Tanaka & Tajiri, but lost. The next day, Newera disbanded. On March 15 at Wrestle Wars 2020 in Ōta, Tokyo, he defended against Heat. On March 29, 2016, Yoshioka defeated Hayata. He teamed up with Sugiura-gun member Hajime Ohara to challenge Ratel's (Hayata & Yo-Hey) for the GHC Junior Heavyweight Tag Team Championship the next day, but they were unsuccessful. On May 5, Sugiura-gun faced off against Kongo, in which Yoshioka faced Haoh in a losing effort, and Yoshioka, teaming with Sugiura-gun (Takashi Sugiura, Kazushi Sakuraba, René Duprée, Hajime Ohara & Nosawa Rongai) lost to Kongo (Kenoh, Masa Kitamiya, Manabu Soya, Yoshiki Inamura, Nioh & Haoh) in an Elimination Match. In that match, Yoshioka was eliminated first. On May 10, after Stinger (Atsushi Kotoge & Kotaro Suzuki) defeated Yoshioka & Ohara, Kotoge betrayed Suzuki, and wished to join Sugiura-gun. Nosawa Rongai then came out and disallowed it, saying he didn't trust him. This led to Yoshioka, Ohara & Kotoge turning on Nosawa, forming their own stable, which became known as Full Throttle. On August 30, at Kawasaki,Go! Yoshioka unsuccessfully challenged Kotaro Suzuki for the GHC Junior Heavyweight Championship. On September 23, Yo-Hey turned on Daisuke Harada, and Atsushi Kotoge defended his old friend, reuniting Momo no Seishun Tag.This caused Ohara & Yoshioka to kick Kotoge, their leader, out of Full Throttle, and welcome Yo-Hey as their newest member. On October 28, at Premium Prelude 2020, Yoshioka & Yo-Hey unsuccessfully challenged Momo no Seishun Tag for the GHC Junior Heavyweight Tag Team Championship. On November 6, Yoshioka signed a one-year contract with Noah.

On February 12, 2021, at Destination 2021 ~Back To Budokan~ in the Nippon Budokan, Yoshioka defeated GHC Junior Heavyweight Champion Daisuke Harada in just over 10 minutes to win the belt for the first time. After the match, he said that he was 'proud to be a part of Noah's Junior division'. On May 2, Yoshioka attacked tag partner Yo-Hey, betraying Full Throttle and joined Stinger with Yoshinari Ogawa & Wrestle Gate alumni Hayata & Yuya Susumu. Other Full Throttle member, Hajime Ohara, joined Daisuke Harada, Atsushi Kotoge & Junta Miyawaki's team. The two stables had an 8-man tag team match the next day, where Stinger won after Susumu pinned Miyawaki. Yo-Hey joined Nosawa Rongai's new unit, Los Perros del Mal de Japon, and Yoshioka met him at Muta the World on June 27, where Yoshioka teamed with Stinger mates Ogawa & Susumu to take on Los Perros del Mal de Japón's Yo-Hey, Nosawa & Dragon Gate's Eita. Yo-Hey pinned Yoshioka after 18 minutes with the Yo-Roll. On July 11, after Daisuke Harada & Hajime Harada defended their GHC Junior Heavyweight Tag Team Championships, Yoshioka & Susumu stepped up to challenge them. The match was scheduled for Cross Over 2021 in Hiroshima on August 1. On July 27, Noah held a 'Junior Team Game' in which Stinger was involved. In Stinger 's match against Noah Regular Army, Yoshioka scored a submission elimination over former tag team partner Hajime Ohara. He made it to the last two, before being eliminated by Daisuke Harada, and thus Stinger was eliminated from the tournament. The reunion of Scramble☆Time (Yoshioka & Susumu) defeated Harada & Ohara at Cross Over 2021 in Hiroshima to each win the GHC Junior Heavyweight Tag Team Championship for the first time each.
