Okinowan Martial Arts were eventually popularized by Gichin Funakoshi, who developed the Shotokan karate style. He took his style of martial arts on tour throughout the country of Japan, demonstrating them at colleges and other community hubs.

It wasn't until after the second World War that karate spread out of Japan into western countries. By then it was "all the rage" throughout Japan.
According to World Bank the population of Japan in 2011 was 127,817,277.
One site estimates the world population of karate practitioners (those that have taken more than one class) is at 23 million, others say 50 or even as high as 200 million martial artists, which means more that just karate.
There are 6 billion people in the world. Using the largest figure, that works out to one person in every 200. The lower number would be one in every 2,000. With the growing popularity of martial arts outside of Asia, and the general movement away from physical activity, the percentage is dropping.

First of all the thing that we call "sport karate" is NOT karate at all. Because all they do there is wear those gloves and punch each other in order to win medals. They destroy the whole philosophy that karate has. They turn a martial art into a useless sport.
