Nobuo Nashiro is a professional boxer who was born on October 12, 1981 in Nara, Japan. He got interested in boxing when his father took him for the first time to a boxing match. He joined the track team in his school to build his stamina, and was finally allowed to fight in high school. He continued to fight when he attended Kinki University; however, he dropped out to start his boxing career.
He started fighting professionally on July, 2003. In 2004, he fought against Hidenobu Honda in August and won. By 2005, he had a match against Seiji Tanaka and won by TKO in the 10th round. After the fight, Tanaka got into a coma and died of subdural hematoma two weeks after. He considered retiring when he heard the news due to guilt. But Tanaka’s father told him to continue his boxing career and to not worry about what happened. After defending the title which he won from Tanaka, he paid him a visit in Tottori, Japan.
In July, 2006, he fought Martin Castillo and won the WBA Super flyweight title by a TKO in the 10th round. That victory made him the world champion in his 8th professional fight. He successfully defended the title by December against Eduardo Garcia of Mexico by a unanimous decision in the 12th round.
Nashiro’s first defeat was against the former WBA Super Flyweight champion, Alexander Munoz at the Ariake Coliseum in Tokyo, Japan on May 2007.
He regained the title in September 2008 against fellow Japanese, Kohei Kono. He defended the title in April 2009 against Konosuke Tomiyama by a TKO victory.
