Those former foes were current Japanese Flyweight champion Takuya Kogawa (26-4, 13) [粉川 拓也] and former champion Suguru Muranaka (23-2-1, 8) [村中 優], who both have notable contests in the coming weeks.
For Kogawa he's ramping up his preparations for July 15th, when he defends his title against Masafumi Otake (15-14-3, 7) [大嶽 正史]. On paper the bout may well look easy for the champion but the truth is that Otake has nothing to lose and everything to gain, whilst Kogawa could potentially see a future world title fight fall apart.
As for Muranaka he'll be in action a week earlier, on July 8th, when he faces Filipino fighter Renoel Pael (19-3-1, 9) in a mouth watering match up. Muranaka, who actually beat Kogawa for the Japanese title back in 2013. Unlike the Kogawa Vs Otake fight this one is regarded as a genuinely tough ask and Muranaka will need to put in one of his career best performances to over-come the Filipino, despite the fact Pael has lost his last 2 bouts to Ardian Diale and Go Onaga.
