Seiyunchin (Seienchin/Seiunchin) as developed and practised by the Academy of Traditional Fighing Arts (see http://www.traditionalfightingarts.com). This embu is "circular" in structure in as much as each side performs the same sequence, with one side starting in the middle. The embu comprises essential bunkai and is built on the tenshin (evasion) derived from that bunkai.
