I met a famous trainer.He said most Japanese boxer don't use their favolite side hand huc brow.
Sakamoto's important damage is by this huk.
When he go his second,looks drunker walking.it's side-brain damage.
Hatakeyama used this and Sakamoto didn't use this.
it's easy to see the different of their damages. his ear brad,and over it ,brain.
Japanese seems like 1,2,1,2,1,2 and go go go go.It's strange for him.
Many japanese boxer cut their front head stair eyes.
Another man answered they crazy.50 years ago they were kamikaze.
