Boulder Aikikai was established by Hiroshi Ikeda in 1980 for the study of the Japanese martial art of Aikido.

The dojo is affiliated with the Aikido World Headquarters in Tokyo, Japan, through the Aikido Schools of Ueshiba organization.

Boulder Aikikai is a federal non-profit educational organization and welcomes all students who can safely participate in our programs. All of our classes are open for free observation.

Boulder Aikikai offers ongoing open enrollment for beginning students with no previous aikido experience during our weeknight 6pm classes (Monday through Friday). There is no need to preregister and you may start on any date. Beginning students will be welcome to attend any combination of weeknight 6pm classes and the Sunday 11:30am class.
