Welcome to the American Shidoshi Kai

The American Shidoshi Kai (ASK) is a fellowship of teachers committed to promoting the Bujinkan martial arts of Masaaki Hatsumi Sensei. Through discussion, cooperation and adherence to the Rules of the Bujinkan, these buyu (warrior friends) share their training and insight.

Founded in 1997, the American Shidoshi Kai has worked to assist and mentor many individual practitioners, clubs, groups and dojo leaders who seek guidance in their budo journey.
