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 Shimbokukai. We are 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.

Beginning April 8th, Ikeda sensei will hold a weekly class in the dojo for those who have completed the COVID-19 vaccine schedule. Contact us first if you wish to attend. Please note that pre-registration through Zen Planner will also be required for this class. Read more.


There are currently three types of classes being offered: virtual, outdoor weapons, and indoor practice. Find the complete schedule on our Classes page.
