A style of Aikido from the "traditional school" taught by Morihiro Saito, based in the Iwama dojo, is generally considered sufficiently stylistically different from mainstream Aikikai that it is named individually, even though it still is part of the Aikikai. Saito-sensei was a long time uchi-deshi of O-sensei Ueshiba, beginning in 1946 and staying with him through his death. Many consider that Saito-sensei was the student who spent most time directly studying with O-sensei. Saito-sensei says he is trying to preserve and teach the art exactly as it was taught to him by the Founder. Technically, Iwama-ryu seems to resemble the Aikido O-sensei was teaching in the early 50s mainly in the Iwama dojo. The technical repertoire is larger than in most other styles and a great deal of emphasis is placed on weapons training.
