At Minimumweight we see one of the most notable changes as former world champion Katsunari Takayama ends up back in the rankings following his loss to Francisco Rodriguez Jr. Takayama has moved instantly to #2 in the rankings behind future OPBF title challenger Kosei Tanaka. Falling out of the rankings at 105lbs is recent contender Masashi Tada who hasn't fought since January when he was clearly beaten by current champion Go Odaira in a bout for the vacant belt. We need to admit we were a little bit surprised not to see Ken Shiro take a ranking here following his great debut win over Heri Amol at the start of the month.
At Flyweight we've seen a few changes though the most notable of those was the swapping of places for former world title challenger Hirofumi Mukai and former champion Toshiyuki Igarashi with Mukai now at #8 and Igarashi falling to #9. Lower down the rankings we've seen Hideyuki Watanabe climb into the rankings at #15 following his draw with top contender Tetsuma Hayashi.
The first new champion we see in the rankings is Sho Ishida who took the Super Flyweight title with an excellent win over Yohei Tobe. Going into the bout Ishida was the top contender and his win has allowed Malcolm Tunacao to being the #1 challenger just above former champion Teiru Kinoshita and former national title challenger Taiki Eto, who now sits just above Tobe, who has fallen to #4. Lower down the rankings we've seen a little bit of a reshuffle with Yusuke Suzuki swapping with Shinichiro Morikawa in the 9 and 10 spots and Takayuki Okumoto has claimed the #14 place following his win over Shota Kawaguchi, who has in turn dropped out of the rankings.
At Bantamweight we saw Kentaro Masuda retain his title with an excellent win over mandatory challenger Konosuke Tomiyama, the loss for Tomiyama saw him dropping all the way down to #5. With Tomiyama dropping down the rankings we've seen small boosts for Ryo Akaho, the new #1, Shohei Omori, Masahiro Ishida and Kohei Oba who all moved up 1 place. Much lower down the rankings was lost Kiron Omura, previously #12, allowing Tatsuya Takahashi to move up a place and Naoto Uebayashi to fill the void at #13.
At Super Bantamweight we've seen Kojiro Takada drop from #4 to #14 allowing for a notable reshuffle near the top. One of the beneficiaries is Yusaku Kuga who jumped from #9 to #6 as he nears a title opportunity, though of course he is behind Takafumi Nakajima, #4, who we expect to fight Hidenori Otake later this year, and Yukinori Oguni who is currently the #1 contender.
At Featherweight we've seen former world champion Akifumi Shimoda drop notably from #2 to #5 allowing Daisuke Yokoyama, Takuya Watanabe and Noriyuki Ueno to each move up a place. The only other changes come at the bottom of the top 15 where Ryo Takenaka has swapped with Hiroshige Osawa for #14 and #15.
At Super Featherweight we have an obvious chance as Masayuki Ito climbed to #4 following his win over Masao Nakamura who has dropped to #7. The only other change has seen Ryota Kajiki swap with Kazuma Sanpei for places #13 and #14.
At Light Welterweight we've seen some very interesting changes at the top. The new #1 contender is Hayato Hokazono who climbs up the rankings following the loss of Shinya Iwabuchi to OPBF champion Keita Obara. The fall of Iwabuchi has seen Shamgal Koichi move up a place to #2 despite his recent loss to champion Hiroki Okada. Another man to come out of this in an advantageous position is the #3 ranked Masanobu Nakazawa who may feel that he has a chance at getting a title fight early next year.
Welterweight has seen a small shuffle with Toshio Arikawa moving above above Yuji Wauke and Shusaku Fujinaka to claim the #9 place.
Light Middleweight has seen a new champion crowned courtesy of Yuki Nonaka's great performance against Kengo Nagashima. Former champion Takayuki Hosokawa is now the #1 contender after Koji Numata claimed the OPBF belt whilst another former champion, Charlie Ota, sits at #2 in the rankings.
There have been no changes at Light Flyweight, Lightweight, Middleweight, Super Middleweight, Light Heavyweight, Cruiserweight or Heavyweight.
