On paper it looks like Furukawa should be the favourite. The younger fighter turned professional in 2012 and fought to a in April that year with Misato Kawaguchi, she then suffered a decision loss to Kei Takenaka but has since gone unbeaten, going 7-0-1. Sadly however when you look through her record there is very little depth to is. Her best win came in February 2015, when she defeated Aiko Yamagishi, with a 4th round TKO. She has also claimed a notable win this year over Christine Latube, however that win is more notable for the fact it was a bout for the OPBF title rather than much about Latube.
Furukawa has won her last 3 by stoppage, though it's really only the win over Yamagishi that actually deserves any attention.
Whilst Furukawa had her record messed up to begin with the same cannot be said of Nishimura who began in 2008 and advanced to 6-0 (1) before taking on her first notable opponent. That opponent was Saemi Hanagata, who stopped Nishimura in the 5th round to claim the OPBF Minimumweight title. Just 7 months later Nishimura would lose again, being stopped by the then WBA Atomweight champion Ayaka Miyao. Since the loss to Miyao she has scored a couple of wins, over-coming Mika Iwakawa and claiming the PABA belt in Thailand against then unbeaten Namphaya Sakpracha.
Although she lacks a big win Nishimura a hasn't embarrassed herself against good opponents, like Hanagata and Miyao, and in fairness to her those losses have proven more than her wins so far.
The bout should be competitive, however we think Nishimura's extra level of competition will help over the finishing line here. Furukawa will likely develop into a better fighter but for now we think Nishimura will simply be that bit too good and that bit too experienced.
