Morihei Ueshiba at the time of his death left his unfinished legacy to one of his sons, Kisshomaru Ueshiba (June 1921-Jan 1999) as is the Japanese iemoto tradition. thus Kisshomaru became the Second Doshu (道主 meaning leader, “way master”) of the Honbu Aikikai Foundation. A number of O’Senseis’ most experienced students went on to disseminate Aikido in schools in their own unique styles (called ryu,流) throughout the world.
However Aikido in the form of Traditional Akikai remains the most prominent form practiced under the founders family. From around 1951 Aikido started to become known worldwide, initially finding its way into Judo dojos and seminars and then later by appointed
instructors and officials from the Honbu, some who would become
permanent residents. In 1967 the original Kobukan dojo building was demolished and replaced with what is the current Honbu dojo building. Under the tenure of Kisshomaru many international ties were established and organizations set up in other countries, and also a forum promoting Aikido excellence. I.A.F. (International Aikido Federation, set up around 1976).
In 1999 Kisshomaru Doshu was succeeded by his son Moriteru Ueshiba, (born 1951). Moriteru Ueshiba is the current doshu guiding aikido into the future with the aide of his son Mitsuteru Ueshiba (born 1980) commonly referred to as “Waka-Sensei”. Mitsuteru Ueshiba holds the position of Dojo Cho at Honbu Dojo.
