what is kote gaeshi?
Kote Gaeshi is simply translated into wrist turn.
Kote litteraly means small hand (wrist) and Gaeshi comes from the verb Kaeru. The meaning is turn or return.
Your opponent can be attacked, taken down and controlled in various manners. Kicks, punches, sweeps and throws and just some of the options.
Generally, it is said that Karate specialises in punching and kicking. It's true to some extent, but not so true if you dig deeper:
We learn the principle through our stances, blocking, punching and kicking. The next step is to learn how they can be used.
If Karate's principle is by far limited to punching and kicking only, it's only limited by your understanding...
Of course in Wado, we practise a blend of Yoshin Ryu Jujutsu and Okinawa Karate giving us more direct access to techniques such as Kote Gaeshi.
