Hasegawa deserves a mention in my opinion...not the best, but a solid BW champion for a long time, good wins against Sahaprom…he wasn´t better than Ohba, Ebihara, Watanabe, but I think he deserves a place between the top 10......
Harada. But Japan's first world champion, Yoshio Shirai, deserves a mention as he is often overlooked. If Pascual Perez hadn't been around he may have had a much longer reign.
