Beyond building the foundation of Shotokan, Funakoshi served as an ambassador of karate, eventually helping to popularise it through public demonstrations and by working to bring it to karate clubs and universities. During World War II western troops discovered Shotokan, so training then spread into more countries. In 1948 Funakoshi established the Japan Karate Association and he remained the head of the JKA until his death in 1957.
In 2005, members of KASKA traveled to Japan and visited Master Funakoshi's grave. It is maintained to this day by students of Shotokan, as his precepts of physical and spiritual discipline and training continue to build strong students throughout the world.
