The more notable of the two shows comes from the Big Wave in Wakayama, thanks to Wakayama Kuratoki Promotions.
The main event here will see OPBF Flyweight champion Jayr Raquinel (9-0-1, 6) defending his title against Shun Kosaka (15-3, 4). The champion, from the Philippines, claimed the title back in March when he stopped Reisuke Nakayama in 9 rounds. In his title win the Filipino puncher looked like a a really exciting hopeful, and at just 21 he is still years away from hitting his physical peak. Despite his lack of years Raquinel showed no fear of going to Japan to win the title and won't be scared of defending it in Japan either. Kosaka has proven to be a credible fighter on the Japanese scene, only losing to good fighters like Tetsuya Hisada, Kenya Yamashita and Akinori Hoshino, but he's not yet scored a win at this type of level and it would take a career best performance to defeat Raquinel and claim the OPBF title here.
In a supporting bout Hyuma Fujioka (9-6-1, 1) will go up against the talented Shohei Kawashima (15-2-2, 3). Coming in to this Fujioka had lost 3 of his last 5, losing decisions to Yuta Horiike and Naoya Okamoto as well as a suffering a stoppage loss to Gaku Aikawa. He's clearly out of form but will know that a win here will give his career a huge boost. As for Kawashima the pressure is on his shoulders to perform here, despite the fact he has lost 2 of his last 3 including a stoppage loss to the aforementioned Gaku Aikawa last year. Kawashima had looked a talented fighter earlier in his career, and had even given Cristian Mijares a real test in 2016, and will be hoping to show those skills here as he attempts to get his career back on track.
The second show is a much lesser card from Hiroshima
On paper the best bout from this card will see Taiyo Inoue (7-3-2, 5) take on Isao Aoyama (10-6-1, 2) in what should be a very competitive bout. Neither of these men are near title level, but rather than fighting in mismatches, either unwinnable ones or ones against novice visitors, they will almost certainly make for a good match up here against each other. It's not quite 50-50, but it's not far off and should be a compelling contest.
A supporting bout on this card will see Hironori Miyake (8-6-1, 1) look to bounce back from a February loss to Kuosuke Sawada as he takes on Wolf Nakano (4-6-4, 1). As for Nakano he is pretty limited and has lost 4 of his last 6, but should be able to test Miyake over the scheduled 8 round decision.
