Different aikido styles, teaching methods and organisations began to appear during the later years of O'sense's life and exploded in to existence after his death, here's a list of the more known styles and affiliations


Morihei Ueshiba - o-sensei aikido The largest aikido organisation, and is led by the family of the founder. Numerous sub-organisations and teachers affiliate themselves with this umbrella organisation, which therefore encompasses a wide variety of aikido styles, training methods and technical differences.

Prominent sub-organisations include numeral national Aikikai, as well as several US based including United States Aikido Federation (USAF) and Aikido Schools of Ueshiba (ASU).


Gozo Shioda aikidoFounded by Gozo Shioda, this branch has a reputation for being the most rigidly precise. Students of Yoshinkan aikido practise basic movements as solo kata, and this style has been popular among the Japanese police.

The international organisation associated with the Yoshinkan style of aikido is known as the Yoshinkai, and has active branches in many parts of the world.


Minoru Mochizuki aikido This form was developed by Minoru Mochizuki, who was an early student of O Sensei and also of Jigoro Kano at the Kodokan. This style includes elements of aiki-budo together with aspects of karate, judo and other arts.

It is now carried on by his son, Hiroo Mochizuki, the creator of Yoseikan Budo.

Shodokan Aikido

Kenji Tomiki aikido Often called Tomiki aikido, after its founder Kenji Tomiki, this style use sparring and rule based competition in training as opposed to most others. People tend to compete to train rather than to train to compete. Kenji Tomiki, an early student of O Sensei and also of Judo's Jigoro Kano, believed that introducing an element of competition would serve to sharpen and focus the practice since it was no longer tested in real combat.

This latter view was the cause of a split with O Sensei's family who firmly believed that there was no place for competition in aikido training. Tomiki said that at no point did O Sensei actually cast him out.

Ki Society

Koichi Tohe aikido The Ki Society, founded by former head-instructor of the Hombu dojo 10th dan Koichi Tohei, emphasises very soft flowing techniques and has a special program for the development of ki.

It also has a special system of ki-ranks alongside the traditional kyu and dan system. This style is called Shin Shin Toitsu Aikido (or Ki-Aikido).

Iwama Ryu

Morihiro Saito aikido Iwama Ryu emphasises the relation between weapon techniques and barehand techniques, and a great deal of emphasis is placed on weapons training. Since the death of its founder Morihiro Saito, the Iwama style has been practiced by clubs within the Aikikai and an independent organisation headed by Hitohiro Saito. Saito sensei was a long time uchideshi of O Sensei, 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 said he was trying to preserve and teach the art exactly as the founder of aikido taught it to him. 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 fairly large.

Iwama Ryu Aikido, currently headed by Saito Hitohiro, is a separate organisation from the Aikikai. The Iwama Dojo is currently affiliated to the Aikikai and is not considered a separate style. Many instructors who were deeply influenced by Saito Morihiro consider themselves Iwama Style, however.
