For those who have missed out on watching Kogawa so far he's a gutsy warrior who gives his all every time he's in the ring. This has lead to memorable battles with the likes of Tetsuma Hayashi in 2012, a 2013 FOTY contender against Suguru Muranaka, a very controversial decision loss in 2014 to Yodmongkol Vor Saengthep and a wonderfully fun to watch victory over Hiroyuki Hisataka, also in 2014.
Sadly for Kogawa he has lost his biggest fights, including the Yodmongkol bout and a decision loss to the great Pongsaklek Wonjongkam, however he has rarely been involved in a bad fight and given his stamina and work ethic it's unlikely his bout with Hayashi will be anything but action packed.
As for Hayashi he's had an interesting career to say the least. He debuted aged 16 in Thailand and ran up a 6-0 (4) record prior to make his Japanese debut more than 2 years after his professional debut. His good start continued until he was 13-0 (8) though since then he has gone 9-7 with recent losses to the likes of Michael Dasmarinas and Marlon Tapales, both coming last year. Sadly he desperately needs a win to remain relevant though is going to have to record a career best to over-come Kogawa.
