The 23 year-old quickly came to the attention of the boxing world when claiming his domestic crown in just three fights and winning the WBO light-flyweight championship after a couple more.
Since then, Inoue has successfully moved up two divisions to reign again and is slowly climbing the pound for pound ratings with each victory.
In his latest triumph, Inoue halted Thailand’s nearly-man Karoon Jarupianlerd, 31, in the tenth round to inflict an eighth loss on his far more experienced opponent.
Also on the bill, bantamweight contender and brother Takuma Inoue scored a unanimous decision over Froilan Saludar to push his own record to 8-0.
Takuma, 20, had to pick himself up off the canvas in the first round but scored two himself in the eight and ninth to eventually cruise to victory 97-90 (twice) and 96-91 on the cards.
A third member of the Inoue family was in action at the Sky Arena in Zama as welterweight Koki Inoue stopped Heri Andriyanto in the second rounds to push his early C.V to 5-0.
The 24 year-old southpaw has now won four of his bouts before the final bell as Koki attempts to makes his own name in the pro ranks.
