Matsumura taught his art to Itosu Ankō (1831–1915) among others.Itosu adapted two forms he had learned from Matsumara. These are kusanku and chiang nan].
He created the ping'an forms ("heian" or "pinan" in Japanese) which are simplified kata for beginning students.
In 1901 Itosu helped to get karate introduced into Okinawa's public schools.
These forms were taught to children at the elementary school level. Itosu's influence in karate is broad.
The forms he created are common across nearly all styles of karate.
