The true meaning and origins of the word 'Oss' are finally revealed!

No matter where in the world you are, enter any karate dojo and the term most frequently heard is 'Oss!' Karate's Universal Codeword is the first thorough examination of the origins and use of this word in the martial arts, and the fascinating story of how it has spread around the globe and to other martial arts disciplines.

The word Oss is used as a basic salutation but has many other meanings and functions as well.

Essentially, Oss has been adopted globally as a universal sign of discipline and respect that reflects the spirit of the martial arts. Use of the word has exploded far beyond karate into other martial arts like judo, aikido, Brazilian jiu-jitsu, kickboxing and mixed martial arts making it arguably the most frequently uttered Japanese word in the world.

Yet ironically, very few martial artists (even in Japan) know the true origins and the deeper meaning behind the term. Although it is universally used, it remains a total mystery to everyone. This book promises to finally reveal the mystery behind the word Oss and its fascinating origins.
