Daiki Kameda became the second brother of Japan's 'brat pack' boxing family to win a world title when he took the WBA flyweight belt by a unanimous decision against Denkaosan Kaovichit on Sunday.
The 21-year-old exacted revenge over champion Denkaosan in Kobe after losing to the Thai last October.
Kameda's older brother Koki won the WBC flyweight title in November and Daiki's victory gave Japan their first sibling world champions.
"I still don't believe it. It's like a dream," a tearful Daiki told reporters before hoisting a piano into the ring and serenading fans with a song he had penned.
"I trained for this fight as if my life depended on it. Honestly the past two years have been tough. This win is a gift to my fans and family."
Daiki was banned for a year for violent behaviour in a failed bid for the WBC crown in 2007 that ended in farce and multiple suspensions.
Kameda, who had branded then-champion Daisuke Naito a "cockroach" in the run-up to the fight, was banned after picking up his opponent and slamming him to the canvas.
Father and former trainer Shiro was booted out of the sport for abusing the referee and Koki escaped with a warning after TV microphones caught him telling Daiki to elbow Naito in the eye.
