Matsumura Seisan literally means ’13’ (Version of Master Matsumura) who adapted original kata of Seisan from Naha-te Schools. Seisan is thought to be one of the oldest kata, being quite spread among other Naha-te schools. Shito-ryu has both ‘Shuri-te’ Version and call it “Matsumura Seisan” and Naha-te version called just “Seisan”. WadoRyu style call this kata “Seishan” and Master Funakoshi named this kata “Hangetsu” in his school.
