the first ever RKKA
International Gasshuku (training camp) was held in 1996. The RKKA was
established by Grant Campbell, Shihan with the support and backing of
the Nakaima family, senior Sensei in Okinawa (many of them students of
Kenko Nakaima), and the senior students of Master Nakaima.
Grant Campbell, Sensei is the first and only American to receive full
training in all aspects of the system and is licensed to teach the art
of Ryueiryu by his teacher Nakaima Sensei, the Soke of Ryueiryu. He was
introduced to and tutored in the system by former World Champion of
The original purpose of the RKKA-USA as set forth then, was to preserve
and protect the true teachings and philosophy of Grandmaster Ryu Ryu Ko
as practiced the Nakaima family. This purpose still remains as the
primary theme of the RKKA today. To this end, Campbell Sensei conducts
daily training and periodically offers seminars and courses in various
locations each year.
