Ryukyu Kempo is not Kyusho Jitsu. Kyusho Jitsu is the Okinawan's combative art of vital point striking (contained within Ryukyu Kempo). Notice that I used the term vital point striking and not pressure point striking. Pressure points are interwoven within Kyusho Jitsu but are not the only thing in Kyusho Jitsu. The eyes are a vital point but not a pressure point for example.
Ryukyu Kempo is many things not just Kyusho Jitsu.
And the introductory katas are the Naihanchi series (Shodan, Nidan, Sandan).
