For a second day running Japanese fans in Tokyo get a huge show at the Ariake Colosseum in Tokyo.
The main event here sees Japanese superstar Naoya Inoue (12-0, 10) defending his WBO Super Flyweight title against Mexican born American based challenger Ricardo Rodriguez (16-3, 5. The bout will be Inoue's 5th defense of the title and it's likely to be his last with his team talking about vacating the title later in the year, ahead of his US debut. The pressure is on the youngster to shine here but Rodriguez is tough and has never been stopped, and will be looking to score a career defining victory here.
The other world title fight here will see IBF Light Flyweight champion Akira Yaegashi (25-5, 15) battle against interim champion Milan Melindo (35-2, 12). The bout is, on paper at the very least, the most interesting of the 6 world title fights taking place this coming weekend and it looks like a genuine 50-50 match up. Of the two fighters Yaegashi is the more proven and the more well known, but he's also the older man and the man with a lot more miles on the clock. Melindo, the less proven fighter, is probably the more technically sound fighter, but a win here would be the biggest of his career by some margin.
The biggest mismatch on this card will see the once beaten Ryo Matsumoto (19-1, 17) battle against Hendrik Barongsay (29-25-3, 18) in what is little more than a stay busy fight for Matsumoto. The talented Japanese youngster looked better than ever last time out, blowing out Hideo Sakamoto in less than 2 minutes, and it wouldn't be a surprise to see Barongsay last a similar amount og time here.
One of the biggest names on the under-card is former multi-time world title challenger Satoshi Hosono (32-3-1, 21), who will take on Masashi Noguchi (12-6-1, 6) in an 8 rounder. This will be Hosono's first bout since losing in October to Jonathan Victor Barros in an IBF world title eliminator. Aged 33 this will probably be the start of Hosono's last run, and he really can't afford another set back. Noguchi is a former Japanese title challenger, who lost in December to Shuhei Tsuchiya, and is the naturally bigger man, but a win here would be his best to date.
In another notable under-card bout we'll see 2012 Olympic Bronze medal winner Satoshi Shimizu (2-0, 2) take on his first domestic opponent, Takuya Yamamoto (8-6, 4). The bout should be a straight forward win for Shimizu, though it's probably fair to say that his eyes are on the future and it's hard to imagine him not fighting for a domestic title before the end of 2017, especially given that he's now 31 and doesn't have much time to waste.
Also on the under-card is the re-re-scheduled meeting between talented youngster Andy Hiraoka (8-0, 5) and Shogo Yamaguchi (10-2-1, 5), who were originally meant to meet in the 2014 Rookie of the Year. The two were also meant to fight earlier this year. Sadly Hiraoka was forced to pull out of both the previous dates but will be looking to prove a point here. As for Yamaguchi he's going to be wanting to take his frustrations out on the younger man in what could be an under-card classic.
There will also be title action in Okinawa, albeit at a lower level as fans get an OPBF title fight.
That that OPBF title fight will see Japan's Seita Ogido (11-2-2, 3) battle unbeaten Filipino Edward Heno (10-0-4, 4) for the vacant Oriental Light Flyweight title. The title was vacated earlier this, by Ken Shiro ahead of his WBC world title fight with Ganigan Lopez, and the bout to crown a new champion does look like an interesting one. Ogido is seen as a promising youngster in Japan, and fought to a draw with the under-rated Jonathan Refugio earlier this year, suggesting there is talent there. Heno on the other hand is a bit of an unknown quantity, despite being unbeaten in 14 bouts, though he did impress last time out as he claimed the PBF title. This bout really could answer questions about both men.
The chief supporting bout here will see Masatoshi Kotani (20-2, 13) hunt an 11th straight win as he takes on Indonesian visitor Musa Letding (12-6-4, 6) in an 8 rounder. Kotani has been unbeaten since a 9th round stoppage loss to Filipino Cirilo Espino in 2012 and looks to have improved significantly since then. As for Letding he's 0-4 out side of Indonesia and will be looking for his first win on the road.
In another under-card bout we'll see the heavy handed Morihisa Iju (10-2, 8) battle against Masaya Kohama (6-5-1, 3). This bout will be Iju's third of the year, but will see him returning to the ring following a March loss to Ryo Kosaka and it's clear he'll be looking to avoid back-to-back defeats. Despite losing last time time out Iju should be favoured given that Kohama has been stopped in his last 3, with the most recent of those coming last July to Yohei Tobe.
There will also be a small card in the Philippines. The card here is very poor overall but the main event does look interesting as Pedro Taduran (10-1, 7) and Philip Luis Cuerdo (9-3-1, 4) battle for the PBF Minimumweight title in a good looking 10 rounder. Coming in the once beaten Taduran has won his last 4 and has rebuilt well following his first loss however Cuerdo was stopped last time out, whilst leading on the score cards.
