What is Ninjutsu?

By Fujita Seiko

A revised 2026 edition of Fujita Seiko's extremely rare 1938 lecture on Ninja and Ninjutsu.

Fujita Seiko 藤田西湖 (1898 1966) began giving public lectures and demonstrations on Ninjutsu in the 1920s. During the 1930s and 1940s, he frequently lectured to police officers, military personnel, and veterans' organizations, as well as giving lectures open to the general public.

Born in Tokyo, Fujita was taught Koga Ryu Wada-ha Ninjutsu by his grandfather and eventually became the 14th head of Koga Ryu Ninjutsu. He was a prolific writer on Japanese martial arts and published numerous books on Ninjutsu and other martial arts.

This 1938 lecture offers a rare glimpse into how one of Japan's most famous Ninjutsu practitioners presented Ninja history and techniques to a contemporary audience.
