Chintō (鎮東) (In Shotokan, Gankaku (岩鶴)) is an advanced kata practiced in many styles of karate.
According to legend, it is named after a stranded Chinese sailor (or pirate), sometimes referred to as Annan, whose ship crashed on the Okinawan coast.
Matsumura Sōkon, a Karate master and chief bodyguard to the Ryūkyūan king, was sent to defeat Chintō.
In the ensuing fight; however, Matsumura found himself equally matched by the stranger, and consequently sought to learn his techniques.
Today, Chintō is practiced in many karate styles like: Isshin-ryū, Wado-ryū, Shūkōkai, Isshin Kempo, Chitō-ryū, Shōrin-ryū, Shitō-ryū, Okinawa Kenpo, Shotokan, Koei-Kan, Gensei-ryū, Goshin Kagen Goju Matsubayashi-ryū, Bushikan-Ryu Karate, and Yōshūkai.
