The Naginata, a pole with a curved blade at its end, was a key battlefield weapon during Japan's long history of warfare. With the advent of peace in the Edo period, the Naginata found new popularity among women, since it allowed attackers to be kept at a distance, reducing any advantage of height or strength. Today, Naginata-jutsu is still practiced mostly by women in Japan. We meet one of the martial art's foremost teachers, and follow a group of schoolgirls targeting the championship title.
