The Aikikai Foundation operates a Hombu dojo in Tokyo, which is also named Aikido World Headquarters or the Aikikai Hombu to distinguish it from the headquarters of other aikido organisations. The location of Aikikai Hombu dojo is in Wakamatsu-cho, Shinjuku, Tokyo, Japan. The dojo was established in April 1931 by the founder of Aikido.
These organisations are normally national aikido organisations that each represent many dojos and many students in a designated country. The grading syllabus of students in these organisations are set by the Aikikai foundation. However, regardless of recognition, all foreign aikido groups remain organisationally independent from the Aikikai Foundation.
Dojo recognised by the Aikikai Fountation (worldwide) are loosely referred to collectively as the Aikikai schools. Their aikido techniques are loosely referred to as Aikikai style.
International Aikido Federation
The IAF organises International Aikido Seminars every four years, facilitating training between aikikai aikido students of different countries, sharing instruction by the world's most senior aikikai instructors, and also providing a channel for official communication with the Aikikai Hombu.
This is associated with the broad base of first generation instructors, who each had their own interpretation of the art, and other influences. Nonetheless Aikikai is often described as a style for comparison with other aikido organisations that either fell foul of or left the Aikikai organisation. Aikikai Aikido is sometimes mistakenly referred to as "traditional" Aikido.
