## Fujita Seiko Hiden Koryubujutsu Feature

**Fujita Seiko Hiden Koryubujutsu Feature** is a landmark 12-page historical research study published in the Summer 1992 issue of *Hiden Koryubujutsu*. Written by martial arts historian **Shimizu Yutaka**, this extensively researched feature centers on *Ninjutsu no Kyo to Jitsu* (“The Illusion and Reality of Ninjutsu”) and critically reexamines the life and legacy of **Fujita Seiko** through original documents, interviews, rare photographs, contemporary publications, and archival sources.

Rather than repeating postwar media sensationalism, the **Fujita Seiko Hiden Koryubujutsu Feature** compares historical evidence with popular legend to present a balanced assessment of Fujita’s lineage claims, martial arts training, public demonstrations, military associations, technical writings, and lasting influence on modern perceptions of Kōga-ryū ninjutsu. It also documents his efforts to preserve traditional Japanese martial arts through historical research, publication, and the collection of rare classical manuscripts.
