?????? I don't get it. I think Sonny Chiba made some movie tribute to Oyama Sensei thou. You typed O'yama earlier probably a typo but like most Irish names the ' in Oyama makes it look like O'connor, or O'reilly, or O'harra. All of which are Irish names, and pronounced OH, YAMA. Or OH, CONNOR. You get the picture, hope that helps.
