Not only has the source informed us of the date of Kogawa's return but also all the other key details.
The bout will take place at the Korakuen Hall and see Kogawa facing off against former foe Tetsuma Hayashi (25-3-2, 9), who Kogawa beat in a thrilling bout back in 2012.
For Kogawa the bout is a chance to defend his belt, as he begins his second reign as the Japanese national champion, whilst for Hayashi the bout is a third shot at a a title. He lost in his first title bout to Kogawa whilst more recently he came up shot against Suguru Muranaka, though Muranaka was stripped prior to that bout for failing to make weight.
Notably the bout hasn't been formerly announced as of yet though is expected to "become official" in the coming weeks with little other than dotting the i's and crossing the t's being needed.
We've included their first bout below for those who missed it.
