  • Brief Biography – Morihiro Saito Sensei (1928-2002)

saito_seiza_260Morihiro Saito Sensei’s  practice of Aikido spanned 56 years and he is one of the most important teachers in Aikido history.  Saito Sensei was a live-in student of O’sensei for more than 20 years at his home dojo in Iwama, Japan.

Saito Sensei spent his teaching life dedicated to preserving the technical style of Aikido as practised and shown to him by O’sensei in the post-war period.  Without his commitment to preserving the Aikido of the Founder and extensive efforts to record and document his teachings, much of the Aikido of O’sensei may have been lost.
