Tsuki no Kata by its very name is a ‘Kata of punches’ and is derived from the characters Tsuki - 突き ('thrust'), no - の ('of') and Kata - 型 ('Kata'). Tsuki also means ‘fortune and luck’. Good fortune and luck does not come by waiting. For every punch in this Kata, envision that a personal barrier is being broken down. Strong, persistent effort directed at problems will bring good fortune, simply persevere.
This Kata was created by Seigo Tada, founder of the Seigokan branch of Goju-Ryu. He was born in 1922 and studied the essence of Goju-Ryu with Chojun Miyagi. In his style he called it Kihon Tsuki no Kata. Historically, Seigo Tada did much to transform Karate into a competitive sport. He established the rules of competition Karate and was awarded several honors. Tsuki No Kata is one of two Kata he invented.
Kyokushin Sensei’s use this Kata to help students to generate striking power in multiple positions, heights and directions. Each time a student punches in this Kata, they should imagine that they are breaking down some barrier.
This very linear Kata seems to come from the Okinawa Shuri-te, itself native to combat techniques in northern China and therefore be considered a Northern Kyokushin Kata. There is an understanding of the different foot positions and the transition from one to the other with the search for stability and work of a movement without changing height. Other deeper concepts such as the work of the Hara and the unlocking of force from the hips are discussed.
In some Kyokushin circles, the Kata is attributed to Tadashi Nakamura because he claims to have it introduced into Kyokushin Karate. However, many speculated that he introduced it into Kyokushin after learning it from his Goju-Ryu background.
More likely is that the Kata has been adopted into Kyokushin by Mas Oyama himself. At the time, Seigo Tada and Mas Oyama were both Goju-Ryu students and knew each other very well.
