Re: Arikawa Sensei
I never saw Arikawa Sensei - when I went to Hombu Dojo three or four years ago his name was still on the teaching roster, but when I finally plucked up the courage to go to one of his classes Toriumi Sensei was teaching in his place. I think he died a few months later. I was disappointed, as I felt, from what I had read and heard about him, that he was one of the true originals in aikido.
I remember years ago Kanetsuka Sensei was musing on who to invite as visiting instructor for the BAF Summer School. He said that he would very much like to invite Arikawa, but he felt the BAF was "not ready yet" for him!
