The great karate master Gichin Funakoshi was a key pioneer in the development of modern karate.
In fact, he was the "prime mover" in bringing traditional Okinawan karate to Japan. He himself was caught in the great wave of social change sweeping through Japan and its prefectures. His contributions include authoring several of the first publications describing the previously secret art of karate, strengthening the connection between character development and karate training, and the development of modern teaching methods. Master Funakoshi supported the realization that karate would evolve from a provincial fighting system to a prominent member of the modern Japanese martial arts.
