Perhaps many of you do not recognize the name Shigeru Oyama as he left Kyokushin many years ago and started his own organization Oyama Karate USA with his brother Shihan Y. Oyama.
If perhaps he had remained in Kyokushin he would have taken over after Sosai passed away.
While he was a member of Kyokushin I trained with him on a number of occasions, he would visit Japan for the All Japan Tournament  and I travelled  to the USA
to prepare for the European and world tournament. He was a hard man to train for, his shinai was always in his hand, he demanded nothing but the best.
