Aiki-ken

Aiki-ken (Kanji: 合気剣 Hiragana: あいきけん) is the name given specifically to the set of Japanese sword techniques practiced according to the principles of aikido, taught first by Morihei Ueshiba (aikido's founder), then further developed by Morihiro Saito, one of Ueshiba's most prominent students. Currently, Iwama Shin-Shin Aiki Shuren-kai is the main proponent organization.

Development of aiki-ken

Much of the aiki-ken syllabus was developed by Morihei Ueshiba (植芝 盛平 Ueshiba Morihei, 1883–1969) at his dojo in Iwama, Japan, at the same time he developed aikido's staff training (called aiki-jō). It is well documented that Ueshiba studied several different styles of kenjutsu (Japanese swordsmanship), but the aiki-ken techniques are predominantly based upon the teachings of the Kashima Shintō-ryu.

Most of the practice of aiki-ken was ultimately systematized not by Ueshiba, but by Morihiro Saito (斉藤 守弘 Saitō Morihiro, 1928–2002), one of Ueshiba's most dedicated students and the person who took over the Iwama dojo after Ueshiba died. Hence the unofficial term "Iwama style" to refer to Saito's style of aikido, incorporating a significant amount of weapons training. In order to preserve the art and to teach an increasing number of students, Saito gathered the teachings of Ueshiba and presented the world with "aiki-ken". The first aiki-ken techniques were published in "Traditional Aikido", Vol I and II by Morihiro Saito, 1973. Saito and his son Hitohiro Saito (斎藤 仁浩 Saitō Hitohiro, born 1957) revived and refined this art.
