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.
In introducing karate from Okinawa to Japan, Gichin Funakoshi changed the name of the kata from Niseishi to Nijūshiho.
This kata is also practiced in Tang Soo Do and is called E Sip Sa Bo in Korean.
Due to its difficulty, this kata is often reserved for advanced black belt level students.
Like its Japanese and Okinawan counterparts, E Sip Sa Bo also translates to “Twenty-Four Steps.” In Shuri-ryu this kata is taught to students achieving the rank of shodan.
