Today Yamaguchi and Hisada took part in their weigh in and both came in at the divisional limit of 108lbs, and both looked in tremendous shape for the bout.
For the 31 year old Hisada a win here will see him getting his first Japanese title fight, giving real relavence to a career that began around 13 years ago and has yet to see him actually getting a shot at the top of the domestic table.
As for Yamaguchi the 27 year old is looking to get himself a third Japanese title fight, following defeats to Masayuki Kuroda and Yu Kimura, he is however looking like a fighter who is struggling with consistency and has lost 2 of his last 4, with both of his wins before close decisions.
It's fair to say Ken Shiro won't fear either of these men, and there is talk that may decide to vacate in search of a world title bout than stay around to face the mandatory in 2017, with both Hisada and Yamaguchi being a step backwards for the talented BMB gym fighter, who has unified the JBC, OPBF and Youth titles.
