Seiunchin (制引戦) is a kaishu kata of Goju-ryu karate. It was taught by Goju-ryu's founder, Chojun Miyagi. Seiunchin can be interpreted to mean "pulling".
Meibukan karateka believe that this kata originated in Hsing-I and that Seiunchin's direct translation has been lost. Meibukan karateka refer to it as "Marching far Quietly".
Seiunchin is a unique kata because only hand techniques are used. Seiunchin uses shiko dachi and incorporates strikes such as the back fist and elbow.
