Held in Honolulu and Kaneohe in March 2013. This was their first joint seminar anywhere, and explored exercises for the cultivation and development of internal power, the terminology and methodology of Aikido Founder Morihei Ueshiba and the practical expression of these principles in Aikido techniques and movement. William Gleason studied Aikido from 1970 to 1980 at the main world headquarters (Hombu Dojo) in Japan and also with Yamaguchi Seigo Shihan. He is the head instructor at Shobu Aikido of Boston. Dan Harden has been conducting seminars for the Aikido Sangenkai in Hawaii since 2010.
