Naoya Inoue rewrote his own Japan record with a 17th straight world title win on Tuesday as the IBF and WBA bantamweight world champion claimed an eighth-round technical knockout of the IBF's fifth-ranked challenger Aran Dipaen from Thailand.
Fighting his first bout in Japan in two years, the dominant Inoue mastered his sixth title defense as the WBA champion and the fourth as the IBF holder against resilient Dipaen at sell-out Ryogoku Kokugikan in Tokyo.
Inoue outnumbered Dipaen with his punches, while the challenger did his best to wind up and unsettle the champion despite bleeding from his nose from an early round.
