Aikikai Foundation, Tokyo
The world headquarters of the Aikikai Foundation is the Hombu Dojo, Tokyo, Japan. The Aikikai Foundation is an association that was established in order to support inheritance of Aikido created by the Founder, to train body and mind through Aikido and to promote Aikido. In 1931, the Founder built a dedicated Aikido Dojo. This was a wooden building approximately 120 square meters (80 tatami mats) in size, called the Kobukan, located in present-day Wakamatsu-Cho, Shinjuku. In 1967 the original wooden structure housing the Aikido Hombu Dojo was replaced by a modern concrete building. In 1973 the building was modernized, and the fourth and fifth floors were added to the building.
It is a common aspiration of aikidoka to travel to Japan and to train in the Hombu Dojo.
