The Minimumweight division is unchanged, just like the Bantamweight, Lightweight and Heavyweight rankings which are exactly like they were a month ago.
At Light Flyweight we see a little bit of a shift in the lower part of the rankings with Takumi Suda (#9) climbing one place the expense of Ryuji Yokoyama (#11). Yokoyama has fallen a couple of place allowing Atsuhi Aburada (#10) to climb a place ahead of his bout with unranked prospect Takeru Kamikubo, a bout that was announced yesterday.
The big move at Flyweight is the removal from the top 15 of Takuma Inoue (previously #3) who has been re-ranked at Super Flyweight. Inoue's removal has caused a number of fighters to move up a place whilst opening up a place for new entrant Yuji Shimizu (#12), who was previously #14 at Super Flyweight. The move up in weight for Takuma Inoue (#4) now sees him in the top 5 at 115lbs where he is sandwiched between former world title contender Teiru Kinoshita (#3) and former world champion Toshiyuki Igarashi (#6), with Igarashi climbing a couple of places at the expense of Ryuichi Funai (#6) and former champion Yohei Tobe (#7) who both fall a couple of places. Overall these rankings have been shaken up in the lower part of the top 15 but the only "loss" is Yuji Shimizu, who as mentioned is now ranked at Flyweight.
At Super Bantamweight we've lost Koji Aoki (previously #9) which has followed a little bit of a shake up in the top 10. The most notable move however is one concerning the now ranked Sho Nakazawa (#14) with the "Sho of Naniwa" being a new entrant. For the most part however the rankings have been little more than reshuffled following Aoki's removal.
At Featherweight the changes come in the bottom part of the rankings with Hiroshige Osawa (#12) and Noryuki Ueno (#13) both climbing a place at the expense of Shinji Takayama (previously #12) who has been removed from the rankings. To fill in the gap we've seen former OPBF challenger Ryo Takenaka (#14) move into the lower end of the top 15.
At Super Featherweight we've seen a notable set of shuffling. The most notables moves here have seen recent title challenger Masayuki Ito (#4) fall following his tight loss to champion Rikki Naito, Matsushita Kento (#1) has been moved up a place, just like former champion Daiki Kaneko (#2). Another notable move was that of Kenichi Ogawa (#8) who has moved above Masao Nakamura (#9) and Shingo Eto (#10).
The changes at 140lbs have been limited with Shinya Iwabuchi (#3) climbing above Masanobu Nakazawa (#4) whilst Jumbo Oda Nobunaga Shoten Petagine (#14) is a new entry and has taken the place of Kota Oguci (previously 14, now unranked).
In the Welterweight rankings the changes have all come in the lower part of the rankings and feature a new entrant. The first change sees Yuji Wauke (previously #9) fall out of the rankings. Wauke's removal has allowed Ryoji Tanaka (#9), Yusuke Konno (#10) and Shusaku Fujinaka (#11) to move up a place each. To fill in the remaining space is the talented Takeshi Inoue (#12), a new entrant.
At 154lbs we've seen a notable shake up with Yuto Shimizu (#2) climbing all the way up from #10 following his surprising win over Takehiro Shimokawara (#6, previously #2). Just below Shimizu is Charlie Ota (#3) who has climbed a place at the expense of Kengo Nagashima (#4). Tadashi Yuba (previously #5) has been removed following his retirement, leaving us with just 10 ranked fighters here, and everyone below Yuba has been moved up a place.
At Middleweight we've lost Ryuji Kanza (previously #9) allowing Hisao Narita (#9) to climb a place.
