Sho-Go
Sho Go is the traditional title system established by the Dai Nippon Butoku Kai to recognize and honor distinguished martial arts practitioners across various disciplines.

The three principal titles within the system are Renshi, Kyoshi, and Hanshi.

Over time, the Sho-Go system has been adopted by many martial arts styles and organizations, including the Japan Karate Federation (JKF), preserving its role as a respected traditional method of recognizing technical excellence, teaching ability, character, and contribution to the martial arts community.
