At Minimumweight we've seen Japanese teenage star Kosei Tanaka (#2) move up a place, almost as if the WBO are setting him up a for a shot at the vacant title if Katsunari Takayama vacates the world title, as is being rumoured. Lower down the rankings Yemeni boxing icon Ali Raymi (#7) has dropped a place. Below him things have changed slightly with Ryuji Hara (#8) being a new entrant and forcing Knockout CP Freshmart (#11) whilst Takumi Sakae (#12) has moved up a place.
The most controversial of changes have come at Super Flyweight where previous #1 contender McJoe Arroyo (now #5) has been dropped despite the WBO stating he was the mandatory in late January. We believe this was due to complaints from Joe Koizumi, representing champion Naoya Inoue. Arroyo's fall has moved Warlito Parrenas (#1) to the top spot. Another near the top has seen Arthur Villanueva (#2) move above Rex Tso (#3). In another change Thailand's Petchbarngborn Kokietgym (#8) has moved up a place.
At Bantamweight we've seen major changes in the bottom part of the rankings. Firstly Filipino fighter Alie Laurel (previously #10) has been removed from the rankings. We have a new entrant in Suriyan Sor Rungvisai (#11) whilst both Shohei Omori (#13) and Ryo Matsumoto (#14) have moved up a single place.
It's not been a good month at Featherweight for Asian fighters as Satoshi Hosono (#14) and Marvin Sonsona (#15) each fell hard whilst Jessie Cris Rosales (previous #15) fellow out of the rankings altogether. In total Hosono dropped 4 places whilst Sonsona dropped 3. We did however see Nonito Donaire (#13) claim a ranking.
At Super Featherweight we've also seen a bit of disappointment as Juan Martin Elorde (#6) has dropped a place.
Japanese Lightweight hopeful Takahiro Ao (#2) has moved up a place, and will likely be considered if the title becomes vacant as is widely expected.
At Welterweight we've seen Azerbaijani boxer Fariz Mammadov (#10) drop 3 places whilst Japan's hard hitting Yoshihiro Kamegai (#12) has moved up a place.
We have good news to report at Light Middleweight where Sirimongkol Singwancha (#8) has moved up 3 places whilst Japanese champion Yuki Nonaka (#11) has also moved up a couple of spots.
There have been no changes relating directly to an Asian fighter at Light Flyweight, Flyweight, Super Bantamweight, Light Welterweight, Middleweight, Super Middleweight, Light Heavyweight, Cruiserweight or Heavyweight.
