Yamaguchi Sensei was a really nice man, so unassuming.
I always liked his style and I also liked Sekiya Sensei, another gentleman. His swordwork was beautiful to watch.
Hope yo u are well, Cheers, Joe.
I didn't have much exposure to Sekiya Sensei - I think I started practising at around the time he moved back to Japan. I enjoyed a day he taught in London during a brief visit a few years later, and KS invited him to lead a BAF Summer School in the early nineties, though he wasn't very active by then and didn't teach much.
My memories of Yamaguchi Sensei are much more vivid, with his visits to Oxford in the mid 1980s.
