In August 2013, Kameda fought for the first time outside of his native and adopted countries when he faced 118-pound WBO world champion Paulus Ambunda in Cebu, Philippines. Kameda pounded Ambunda with body shots and dominated the 12-round fight, winning a unanimous decision to become the third Kameda brother to earn a world title. When brother Daiki beat Rodrigo Guerrero in September 2013 to become a world champion at 115 pounds, the Kamedas became the first trio of siblings to ever hold titles simultaneously.
