I had the great fortune to study with Yoshigasaki
Sensei in Seattle on August 14-19, 1995 at the National Ki Conference.
He was a Uchi Deshi with Kashiaway Sensei
in Japan prior to relocating to Europe. He is functionally fluent
in 7 languages. While Yoshigasaki Sensei is a very good teacher,
his tactics are a bit unnerving and unorthodox. Yoshigasaki Sensei
is Nana Dan (7th degree black belt) in Ki-Aikido and Okuden in Ki Development.
I would heartily recommend studying with him should he ever return to the
States, although you should expect the unexpected when he teaches.
