Details of the spar haven't really been released but from what we understand Inoue felt the session was a good one and with Kogawa being known for his work rate and heart we can have a good guess as to just how hard the youngster was pushed.
Kogawa was the third notable fighter that Inoue has sparred in recent days having also shared ring time with Yohei Tobe and Tetsuma Hayashi and it's fair to say that these sessions will all help develop the rising young star of Japanese boxing. Whilst they were certainly held to help him prepare for his upcoming fight with Samartlek Kokietgym we think the effects may be longer lasting.
As for Kogawa this will have helped him shake some serious rust having been out of the ring since his very controversial loss, in a WBA interim Flyweight title fight, to Yodmongkol Vor Saengthep. Thankfully this sparring session suggests that Kogawa is gearing up to return to the ring for his next fight, even if it hasn't yet been announced.
