At Minimumweight we've had some interesting developments with Denver Cuello (#1) climbing a single place, along with Kosei Tanaka (#4) following the unexpected loss of former #1 contender Carlos Ortega. Lower down the rankings we've seem Ryuji Hara (#12) fall a place whilst recent challenger Jeffrey Galero (previously #12) has dropped out of the rankings, following his loss to Wanheng Menayothin on February 5th.
The Light Flyweight division saw a new champion crowned at the end of December when Pedro Guevara stopped Akira Yaegashi (now #5 previously #3), this set a chain reaction of changes at the top of the rankings which has seen Filipino pair Jonathan Taconing (#3) and Rey Loreto (#4) both move up a couple of places to climb over Yaegashi. Notable behind Yaegashi is his stablemate Takuma Inoue (#6) who climbed 4 places following his excellent win over Nestor Daniel Narvaes. Sadly Takuma's rise has come at the expense of Japanese champion Yu Kimura (#8) who has fallen a single place. Lower down the rankings we see yet another Japanese contender as Ryo Miyazki (#14) re-enters the top 15. Also in the bottom part of the rankings we've seen Filipino fighter Rene Patilano (#12) climb a place.
Despite the swathe of changes at 108lbs we've not really seen many changes at Flyweight where the only move of note has seen Kazuto Ioka (#7) climb over compatriot Koki Eto (#8).
At Super Flyweight we again see numerous changes. The first of those has seen Hong Kong's Rex Tso (#8) climb a single place. Not much lower down we've seen Ryo Matsumoto (#10) climb in into the top 15 following his win over Rusalee Samor on December 13th to claim the OPBF title. Incidentally Matsumoto has climbed above a couple of OPBF champions in the process with Malcolm Tunacao (#11) and Arthur Villanueva (#12), who both remain where they were. To round of the top 15 is another new entry, Sho Ishida (#15) who is known to be eyeing up a world title shot this year.
The first change of note for us in the Bantamweight division has seen Youth Silver champion Petch Sor Chitpattana (#8) drop a place. Strangely Ryo Akaho (#11) has dropped a couple of places whilst compatriot Shohei Omori (#13) has dropped a single place. The most interesting revelation here however is that Kentaro Masuda (#14) has climbed in to the top 15 making his bout with Omori incredibly important, much more so than just a typical national title bout.
The notable change at Super Bantamweight has seen Japanese youngster Shun Kubo (#15) break into the rankings, strangely however this appears to have come at the expense of Albert Pagara (#17, previously #15) who really has been dropped in a very confusing manner.
In the Featherweight division we've seen Filipino puncher Marvin Sonsona (#3) fall a single place whilst his compatriot Dennis Tubieron (#15) has entered the rankings, ahead of his fight with with Josh Warrington (#12) on April 11th
In the Super Featherweight division we see only a single Asian ranked in the top 15, though that fighter has moved up this month. That is OPBF champion Jomthong Chuwatana (#9) who has gained 3 places following his recent win over Daiki Kaneko.
At Lightweight we see a number of notable changes since the last rankings were released, notably included a new champion with Jorrge Linares claiming the title in late December. Linares's win has allowed stable mate Takahiro Ao (#4) to move up a place though the big winner was Masayoshi Nakatani (#8) who moved up 4 places whilst Yoshitaka Kato (#12) managed to move up 2 places.
The Light Welterweight rankings have only had a small change of note with OPBF champion Keita Obara (#11) dropping one place.
In the Welterweight rankings Japan's Yoshihiro Kamegai (#14) has dropped a couple of places.
At Light Middleweight Filipino fighter Dennis Laurente (#10) has climbed 3 places after claiming the OPBF title in late December and ending the long career of Tadashi Yuba.
At Middleweight Ryota Murata (#8) has climbed a single place and now sits just behind former world champions Daniel Geale and Sergio Martinez.
The Super Middleweight, Light Heavyweight, Cruiserweight and Heavyweight divisions feature no ranked Asian fighters.
