It was taught by Goju-ryu's founder, Chojun Miyagi, who in turn learned it from his teacher, Kanryo Higaonna.
[1] Meibukan karateka believe that this kata originated in xingyiquan and that Seiunchin's direct translation has been lost.
Seiunchin was brought to Isshinryu, another Okinawan style, by Tatsuo Shimabuku: he learned it from Chojun Miyagi while studying Goju-ryu.
The word "Seiunchin" is written as "Control Pull, Fight" by many Okinawa Gejuryu stylists, as well as lahinryu teacher Master Angi Uezu (son in law of Shimabuku Tatsuo).
Seiunchin Kata contains no kicking techniques but builds strength and stamina through its breathing and strong muscular tension.
