Built upon the philosophical principals of Buddhism and Taoism and adapted to the Japanese mentality by schools of Zen, traditional Kyūdō is practiced extensively today in Japan and by thousands of people worldwide.

Competitors, through the spirit and dignity of their shooting, should be able to move, emotionally, those who watch. Competitors are scored based on the continuous flow of their movements from walking to breathing, various technical aspects, and its overall beauty.
