Prior to becoming a professional wrestling, Yoshino was an accomplished high school baseball player. Once he realized his passion was in wrestling, he participated in the "amateur" pro wrestling company JWA Kansai before entering venturing to Mexico and enrolling in the Ultimo Dragon Gym.
Originally debuting as part of the Toryumon 2000 Project (T2P), it was clear that Yoshino’s speed and chiseled physique were the things that would make him stand out. Indeed, as his original gimmick was modeled after that of Tarzan, he quickly gained the nickname Lightning in the Jungle, which is still used to this day. To go along with this gimmick, he also brought with him to the ring a pet gorilla named Venezia.
Within T2P he was considered the number two star, second only to Milano Collection AT. When Milano began to form a unit, it was only natural that he would be the first one approached. Yoshino accepted Milano’s offer and changed his name to YOSSINO, to represent his (obvious) Italian background, to form the Italian Connection. As part of this new force within T2P, YOSSINO would play a major role in the ensuing T2P invasion of Toryumon, and more specifically with Crazy MAX.
The two factions would go on to feud until the Italian Connection were able to win the UWA Trio Tag Titles from Crazy MAX at the Toryumon vs T2P PPV. This achievement cemented the dominance of the Italian Collection and proved that T2P were here to noticed. After losing the titles back to Crazy MAX a few months later, YOSSINO entered into a feud with K-ness., which included many highly regarded matches and is considered one of the Dragon System’s best feuds.
After Ultimo Dragon left the company, taking the Toryumon name with him, the newly formed Dragon Gate needed to create titles of it’s own. The trio titles were named the Open The Triangle Gate Championship and YOSSINO, along with fellow ItaConn members Milano Collection AT and Anthony W. Mori were able to become the very first champions. However, the Italian Connection, having already split in half once, were finally dissolved when Milano decided to leave the company. Now left to his own devices, Yoshino entered the the very first Open the Brave Gate tournament and was able to win becoming the first Brave Gate Champion. It would prove to be a title that he would come to know a great deal throughout his career.
Soon after this however, Yoshino would turn heel once more and join the newly formed Blood Generation. He reverted to his given name and dropped the Tarzan gimmick and cut his hair short. This would prove a new direction for Yoshino as he would also later leave BloodGen with Naruki Doi and Gamma to form Muscle Outlaw’z, the largest heel faction Dragon Gate has ever known.
During his time with MO’z, he would begin teaming with co-leader Naruki Doi (Gamma being the other leader) to form the tag team known as Speed Muscle. Speed Muscle would see unparalleled success on the tag circuit, both within and outside of Dragon Gate itself. They were also crowned the very first Open the Twin Gate Champions as well as winning the first Summer Adventure Tag League, which they would also win two more times. They even succeeded in claiming the GHC World Junior Heavyweight Tag Team Championship from Pro Wrestling NOAH, further exposing them as an elite tag team.
However, it was increasingly clear that Speed Muscle and the rest of Muscle Outlaw’z were on different paths. Speed Muscle was seeing a great deal of success, and were able to win without resorting to dirty tactics, something MO’z certainly considered their mantra. This rift would continue to escalate until Speed Muscle would turn on MO’z, causing fellow member Yasushi Kanda to lose his hair. The two sides would part, with the MO’z remnants forming Real Hazard, and Speed Muscle forming WORLD-1 along with BxB Hulk, Naoki Tanizaki, and m.c.KZ.
WORLD-1 would turn out to be the new major babyface group in the company, and Yoshino played a major part in that. He would go on to win multiple Brave Gate, Twin Gate and Triangle Gate championships. He would also make his presence felt outside of Japan, displaying his breathtaking speed in TNA during their World X Cup series as well as participating in the 2008 PWG Battle of Los Angeles tournament. Yoshino would also play a role in developing Dragon Gate USA by appearing in nearly every show. His contributions would be recognized when he and PAC became the first Open The United Gate Champions to open 2011.
But it wasn’t until he faced YAMATO at the World PPV in 2010 that he finally tasted Dream Gate success. It was clear that Yoshino was truly, finally, considered number one. Soon after this, however, long time partner Naruki Doi had turned on Yoshino and left WORLD-1 to form the super heel group Blood Warriors with CIMA.
Yoshino had a fairly memorable run as Dream Gate Champion, successfully defending the title four times and holding it for 277 days. He would lose the title to Masaaki Mochizuki, who immediately invited Yoshino and WORLD-1, who had been forced to dissolve earlier the same night, to form a unit that would eventually become Junction Three and combat the growing threat of Blood Warriors.
Yoshino would take a bit of a backseat as Mochizuki was the clear leader and ace of the group, but his presence was still appreciated as he joined Gamma and YAMATO in claiming Triangle Gate. Much of Yoshino's battles were against his old partner Naruki Doi and the two would battle for the belts before was successful in winning them teaming with Naoki Tanizaki and Kzy.
Speed Muscle Reunion
In February 2012, Junction Three lost an elimination tag match where the losing team was forced to disband. Following this, he noticed that Doi was not particularly pleased with the direction Blood Warriors was going since Akira Tozawa led a coup that forced CIMA out of the group. Not long afterward, Tozawa changed the group into MAD BLANKEY and they proceeded to assault Doi. Doi was saved by Dr. Muscle, who performed a Torbellino. It was clear Yoshino was under the mask and he asked Doi to reform their legendary tag team. Doi accepted.
At the same time, they brought in PAC, Ricochet, and Rich Swann to form a unit that would eventually be known as WORLD-1 INTERNATIONAL. The group would quickly make their presence felt by winning Triangle Gate, but suddenly Yoshino found himself having to carry the group's name alone for a short period when Ricochet had to return home to the United States for an extended period, PAC ventured to New Japan to compete in the Best of the Super Juniors tournament, and both Naruki Doi and Rich Swann were sidelined for a while with injuries.
