Shinsuke Yamanaka

Amateur career

Yamanaka became interested in the sport of boxing as a result of seeing the likes Joichiro Tatsuyoshi, Mike Tyson, and Naseem Hamed on TV. He amassed a 34-13 amateur record. During this time, he defeated future world champion Takahiro Ao. However, Yamanaka has referred to his amateur career as "average".

Professional career

Yamanaka trains at the storied Teiken Gym in Tokyo under former pro boxer and Japanese nation champion Yamato Shin. Yamanaka has currently made twelve successful consecutive defences of the WBC and The Ring bantamweight titles and is currently ranked 9th in The Ring (magazine) Pound for pound listings.

Early career

Yamanaka debuted at the age of 23 in Tokyo's Korakuen Hall, where he would fight 14 of his first 15 fights. Over his first 8 pro bouts he amassed a 6-0-2 with 2 razor-thin decisions. Yamanaka would improve on the ring by stopping his next 5 opponents. On June 20, 2010, Yamanaka defeated Mikio Yasuda to win the Japanese bantamweight title. He'd only defend that title once against highly touted prospect Ryosuke Iwasa, stopping him in 10 rounds.

Yamanaka vs. Esquivel

Yamanaka captured the vacant WBC bantamweight title in his first world title shot against Mexico's Christian Esquivel via an eleventh round technical knockout after knocking him down in the sixth and eleventh rounds at the Yoyogi National Stadium Second Gymnasium in Tokyo on November 6, 2011. Yamanaka was presented with the Rookie Award both in the forty-fourth Japan Professional Sports Awards and Japan’s Boxer of the Year in 2011.

Yamanaka vs. Darchinyan, Rojas

Yamanaka's first defense came against former flyweight and super flyweight titlist Vic Darchinyan on April of 2012. Darchinyan had unsuccessfully attempted to become a 3-weight world champion twice before, losing by decision to Abner Mares and Anselmo Moreno. Yamanaka won the fight by unanimous decision (117-111, 116-112, 116-112), but Darchinyan would become the first fighter to last 12 rounds against the WBC champion since 2008. Yamanaka defended his title once more in 2012 against Tomas Rojas, knocking the former WBC super flyweight champion out in the 7th round with a left-hand cross.

Various defenses

Yamanaka would go on to face Malcolm Tuñacao on his third defense. Yamanaka would end up winning by technical knockout on the 12th round after knocking Tuñacao down three times in the course of the fight. Yamanaka's fourth defense came against José Nieves, whom he knocked out in the first with an overhand left. Yamanaka's final defense of 2013 would be against Alberto Guevara. Yamanaka would once again knock his opponent down three times before finishing him with a left-hand in the 9th. In 2014, Yamanaka notched 2 more defenses. The first came against Stephen Jamoye, whom he knocked down 4 times before stopping him in the 9th round. The second one would come against Suriyan Sor Rungvisai. Yamanaka dropped Sor Rungvisai 3 times but was unable to finish him, winning by unanimous decision (116-108, 115-109, 114-110) but ending a 5 fight knockout-streak. His first defense of 2015 came against Diego Santillan, who touched the canvas twice before being stopped on the 7th round.

Yamanaka vs. Moreno

Yamanaka would run into his toughest fight yet in his ninth title defense against former WBA champion Anselmo Moreno. The fight took place on September 22, 2015 in Ōta, Tokyo. Moreno, a classical out-boxer, kept Yamanaka from landing his signature left-hand using his jab and movement to neutralize the WBC champion. Moreno would pull ahead on the scorecard by landing combinations during the middle rounds. Yamanaka and Moreno traded power punches in the latter third of the fight, with Yamanaka seemingly getting the better of the fight during this stretch. The final round would end with both fighters visibly tired and resorting to holding. With no clear winner, the fight was ruled a controversial split decision (115-113, 115-113, 113-115) won by Yamanaka. The three judges were all from the United States, but many observers and Moreno himself felt they had favored the local fighter.

Yamanaka vs. Solís

Yamanaka's next defense would come against Liborio Solís on March 4, 2016. Solís proved to be another tough test for the WBC champion. Yamanaka sought to establish himself early, winning the first round and knocking his opponent down in the second. However, Solís would come back and drop Yamanaka with a right-hand in the third round. Yamanaka seemed to recover, but late on that same round he was dropped again by a well-timed counter from Solís. Yamanaka would rally after that round, proceeding to drop Solís once more in the 9th round. Both fighters would continue trading punches until the final bell, but Yamanaka had dominated most of the fight and he was given a unanimous decision (117-107, 117-107, 117-107).

Yamanaka vs. Moreno II

Roughly 2 months after the Yamanaka-Solís bout, Anselmo Moreno had defeated previous WBC title challenger Soriyan Sor Rungvisai to become Yamanaka's mandatory challenger, setting up a rematch. The rematch would take place at the Edion Arena on September 2016. Moreno tried to stifle Yamanaka with his jab once again but Yamanaka had more success landing counters, even dropping Moreno once on the opening round. The two fighters would go on to trade knockdowns, with the defending champion going down in the 4th and the challenger going down in the 6th. The seventh round proved to the decisive one, as Yamanaka knocked Moreno down twice more before the referee waved the fight off. With this seventh-round technical knockout victory, Yamanaka won the vacant The Ring bantamweight title.

Yamanaka's latest defense came against Carlos Carlson, whom he also defeated via seventh-round TKO on March 2, 2017.

Yamanaka vs. Nery

Yamanaka's 13th defense would come against #1 WBC contender Luis Nery in Kyoto. With this fight, Yamanaka sought to equal Yoko Gushiken's record for most successful defenses by a Japanese world champion. The bout started with both fighters trading back and forth combinations, but at the start of the fourth round Nery rocked Yamanaka with a left cross. After a brief respite in which Yamanaka seemed to regain control, Nery continued pummeling the defending champion, who was unable to defend himself. Yamanaka's corner eventually rushed into the ring to protect their fighter, giving Nery the win. The fight was seen by an audience of over 7 million people in Japan. In a press conference after the fight, Yamanaka stated that he was unhappy with the stoppage but he didn't blame his trainers for it. Yamanaka also said he was considering retirement but he was open to a rematch with Nery.
