I thought that Kyokushin Karate had many unique Kata but I have learned that two of them were originally from Goju Ryu and Shito Ryu. These kata are Tsuki no Kata and Yantsu (Ansan). I have looked up the information on Wikipedia and Youtube.
Tsuki No Kata :
Tsuki no kata comes apparently from Seigokan Goju Ryu by Seigo Tada and exists in that system under the name kihon tsuki no kata. Here are links to the Seigokan version and the Kyokushin version.
Apparently, Yantsu comes from Ansan, a Shito ryu kata. Here are links to the Shito ryu version and the Kyokushin version.
Have any of you known these kata under these names? Are they well known and widely studied in Goju-ryu and Shito-ryu? I've been looking for bunkai for these kata for a long time.
