The Open Aikido Association was founded by Chris Diacopoulos, our chief instructor, in 1990 as an independent organisation dedicated to the study of traditional aikido, borne out of the instructors and membership’s desire to practice simple, effective aikido in the spirit of common practice. With the help and encouragement from friends in the aikido community, we have built contacts with many aikido groups in the UK and around the World.

From inviting Hiroaki Kobayashi Sensei to London in 1999 to run our first international seminar in London, we eventually were honoured in 2002 to be offered the opportunity to become the official UK representatives of Aikido Kobayashi Dojos, Japan. This relationship carried on until 2014 when we decided to follow a different path after 12 years of successful seminars and a lot of practice.

From September 2014 we joined a new organisation and became affiliated with the Yokohama International Aikido Club, following the teaching of Mimuro Atsushi sensei (Aikikai 7th dan shihan). Our training keeps a direct input from Japan and a link with the Hombu Dojo, the home of traditional aikido.

We aim to continue this success going forward. Our practice is friendly, informal, vigorous and (we hope) fun.
