Kōki Kameda

Japanese boxer

On December 20, 2006, in a highly anticipated rematch, Kameda decisively defeated Juan Jose Landaeta at Ariake Colosseum in Tokyo, Japan. Kameda employed a rather different boxing style from the one he used back in the title match on August. Kameda outboxed Landaeta for most of the match using his quickness and accuracy, and won by unanimous decision. Kameda vacated his Light Flyweight Championship to move up to the Flyweight division on January 22, 2007.

Koki Kameda beat Daisuke Naito on November 29, 2009, for the WBC and lineal flyweight championships.

On March 27, 2010, Koki Kameda fought Wonjongkam to unify the WBC Flyweight championship and interim WBC Flyweight championship. The winner would also claim the vacant The Ring's Flyweight championship. Wonjongkam defeated Kameda by a 12 round majority decision to become the WBC, The Ring and Lineal Flyweight champion.

On December 26, 2010, Kameda went up to the Bantamweight weight class and fought Alexander Munoz of Venezuela for the vacant WBA Bantamweight Regular Title. Kameda defeated Munoz by unanimous decision to win the title. In May 2012, Kameda status was changed to "Champion in Recess", as he claimed an injury that prevented him from fighting mandatory contender and Interim Champion Hugo Ruiz. Kameda was restored to Champion in November 2012, but vacated his title in December 2013, following a call for a unification match with WBA Super Champion Anselmo Moreno, in order to move down to the super flyweight division.

Kameda is often criticized for his flamboyance, immaturity, and lack of respect both inside and outside the ring. He has never spoken courteously towards anyone in his numerous TV appearances, (considering that the Japanese language has tenses specifically used for courteous speech) and often taunts opponents with insulting presents and language. Criticism also revolves around his boxing skills and sportsmanship. The fact that Kameda's first six opponents had a combined record of 0–18 brought much criticism during the early part of his professional career. Many Japanese boxers, including former WBC Super flyweight champion Masamori Tokuyama and WBC Minimumweight title Eagle Kyowa, have stated that they could easily defeat Kameda if given a chance, and that his boasting and popularity are greatly out of proportion with his actual skills in the ring. There was an outcry from the Japanese public about his first bout against Landaeta being fixed. Former world champions Guts Ishimatsu and Yasuei Yakushiji have commented that they believe Kameda lost the fight. He was also involved in the controversy surrounding his brother Daiki during his fight with Daisuke Naito. Koki escaped with a warning about advising Daiki to elbow Naito in the eye. His brother was suspended from fighting for one year and his father was suspended indefinitely for the incident. It was originally rumored and intended that Kameda would fight then WBC Light Flyweight title holder, Brian Viloria, in a WBA/WBC unification title fight. However, Kameda's controversial decision over Landaeta in the first match and Viloria losing to Omar Nino made the match difficult to produce further talks. He is dubbed as (浪速の闘拳) in Japanese. Naniwa is a former designation of Osaka. The nickname denotes "The Fighting Fist of Osaka", though it is sometimes derided by his anti fans as "浪速の逃犬" (pronounced the same as the original one), which means the run away dog of Osaka.
