Do you think Masayoshi Nakatani is the most good Japanese challenger without a World belt of the last years ? His level was more a world level than Jin Sasaki ? Masayoshi Nakatani amateur record : 45 victories (30KOs) - 15 loses. professional record : 20 victories for 3 loses (14KOs) (he lost only against Lomachenko & Teofimo Lopez two of the most greatest lightweight in all history and at his end of his career he lost against his compatriot Shuichiro Yoshino). OPBF champion like Jin Sasaki he defended his belt against same level or tougher challengers like Yoshitaka Kato, Krai Setthaphon (prime), Izuki Tomioka, Futoshi Usami...
I don’t think he was the best recent Japanese fighter without a belt at all, but I definitely feel he was better than Jin Sasaki. Out of the recent Japanese fighters at 135/140/147, I think Hiraoka is the best to have not won a title, personally. I view Sasaki as a journeyman who was gifted a title shot for beating relatively low level opponents in a weak domestic scene.
I like Sasaki but when he stepped up to world level it was clear he was out of his depth against Norman (and disclaimer, I was one who was open to Sasaki upsetting Norman). Nakatani held his own against Teo, and he always has the accolade of starching that vermin Verdejo. On balance, at world level Nakatani was more proven.
Andy Hiraoka can have his world belt this Saturday, but I agree that he is one of the best Japanese prospect.
I think Hiraoka is different. I don’t normally back Japanese guys above 130, but he looked great last time out.
