Inoue, nicknamed ‘Monster’, exploded onto the world scene in just his fifth fight last year and has ripped through the 108 and 115 pound divisions since.
Now 9-0, Inoue has the potential to go through even more weight divisions, although a move down to flyweight for a clash with Roman Gonzalez would no doubt be the most eye-catching and lucrative.
In the co-feature, ex-minimumweight and flyweight title holder Akira Yaegashi became three-weight world champion with a decisive victory over Javier Mendoza.
Yaegashi, 32, picked up the IBF light-flyweight title with a 120-107, 119-109 and 117-111 triumph with the officials and now boasts 23 wins from 28 contests.
Satoshi Hosono defeated former world champion Akifumi Shimoda via a split decision to retain the Japanese featherweight title for the fifth time.

Ryo Matsumoto and Daichi Kawabuchi both scored stoppages to remain undefeated on the bill, whilst Araki Yamazaki won a four-rounder over Kabereen Yuya on points.
