The Super Flyweight division is widely regarded as one of the best in the sport, even with Naoya Inoue leaving the division to make a mark at Bantamweight. Sadly though the division is a frustrating one with a number of fighters making themselves unavailable for big fights.
One such fighter is IBF Super Flyweight champion Jerwin Ancajas (28-1-1, 19), who signed with Top Rank in late 2017 and froze himself out of fights against the likes of Inoue and the fighters who are currently tied to HBO. As a result of being frozen out of specific fights we won't see Ancajas in with a notable name, and instead he will be kicking off his 2018 with an IBF world title defense against Israel Gonzalez (21-1, 8). The talented Ancajas had an excellent 2017, Going 3-0 (3) for the year and beating the likes of Jose Alfredo Rodriguez, Teiru Kinoshita and Jamie Conlan and will be looking to continue his great momentum here. Sadly though Gonzalez, who the IBF miraculously ranked #10, feels like a huge step backwards, with the Mexican challenger really doing little to show he belongs at this level. The bout has been put together as a showcase for Ancajas on US TV and should be a real chance to shine for the Filipino, who will hopefully get better competition later in the year.
At the Korakuen Hall we see the first of this year's Champion Carnival bouts, as Japanese Super Featherweight champion Masaru Sueyoshi (16-1, 10) defends his title against Ken Osato (13-1-1, 4). The bout will be Sueyoshi's first defense of the title, which he won last October with a decision over Ribo Takahata whilst Osato will be having his first title bout. In 2017 we saw Sueyoshi have a great year, going 3-0 (2) but left questions to be asked with some of his performances and he will look to answer them here. Osato had a great 2017 himself, going 3-0 (1) with notable wins Sho Nagata and Satoru Sugita, with the Sugita win earning Osato a shot at the title. This should be a very skilled bout, with both men being very talented, and a very evenly matched bout, between two top domestic fighters.
In the chief support bout Japanese ranked Welterweight Yuki Nagano (12-2, 9) will face off with Thai visitor Najilek Sor Boonlieng (0-1). Coming into this Nagano is riding a 10 fight winning run, and is closing in on a title fight. Although not the greatest of fighters Nagano is a big puncher and should have significant size over the Thai, who will be lucky to last more than 3 rounds.
A second supportig bout of note will see unbeaten hopeful Haruaki Kamiya (7-0, 3) take on win-less Thai Chatchai Phonlemueangdee (0-3). Kamiya has had a real slow burn of a career, fighting only 4 times since the end of 2014, but if he gets sorted he could go quite far. Sadly bouts like this won't help him develop or move towards the bigger bouts than his early promises suggested he could end up having. As for the Thai he has been stopped in all 3 of his defeats.
In the Thai capital fans will be able to see Chinese puncher Pui Yu Lim (5-0, 5) take on Indonesian journeyman Ramadhan Weriuw (17-9-1, 15) in a bout for the WBC Interim Asian Boxing Council Middleweight title. On paper this is a step backwards for Lim, who has already scored wins over better fights than Weriuw, but with 5 fights last year Lim is a busy fighter and could use this interim title to help secure more meaningful bouts down the line.
