Overall the changes have been minimal with many divisions remaining unchanged from a month ago.
The first change comes Light Flyweight where former title challenger Yuki Chinen (previously #4) has been removed from the rankings. We believe this has been due to inactivity with Chinen having not fought since last June when he lost in a title shot at national champion Yu Kimura. Chinen's removal has seen everyone below him climb a place including former world champion Ryo Miyazaki (#4).
At Flyweight the changes have been minimal with former Light Flyweight champion Masayuki Kuroda (#6) switching places with Myung Ho Lee (#7). This move has come after Kuroda's recent victory over Kazuaki Moriya.
The next change comes at Super Bantamweight where Taiki Minamoto (#8) has switched places with Koji Aoki (#9).
At Middleweight we see the re-ranking of former champion Tomohiro Ebisu (#4) who was previously ranked at #1 at Super Middleweight, in fact he was the only ranked Japanese Super Middleweight in the last rankings.
