Nijūshiho or Niseishi Nandan sho (二十四歩) (Japanese: Twenty-Four Steps) is an advanced kata practiced in Shotokan, Shitō-ryū, Chito-ryu , Ryūei-ryū Shuri-ryū and Wadō-ryū karate. The origin of Nijūshiho is unknown, but it is presumed that it originates from the Aragaki group like Sochin and others. This is shown through the similarity to Unsu. In introducing karate from Okinawa to Japan, Gichin Funakoshi changed the name of the kata from Niseishi to Nijūshiho. Both names mean "Twenty-Four Steps." In Shuri-ryu this kata is taught to students achieving the rank of shodan.
