This historical archive entry preserves the rare March 1957 issue of Manga Yomiuri (漫画読売, Issue No. 5). Distributed as a special supplement block by the Shukan Yomiuri (週刊読売別冊) weekly magazine network, this specific vintage publication stands as a critical media asset for martial arts researchers and historians studying postwar ninja heritage. While the striking geometric cover art of two stylized birds was illustrated by famed contemporary cartoonist Taizo Yokoyama (横山泰三), the interior pages contain extraordinary, historically significant instructional material provided directly by the legendary Koga-ryu grandmaster.

Following the opening cover layout, the issue transitions on pages 9 through 13 into a high-quality photogravure section titled “Boku wa Ninjutsu-tsukai” (ボクは忍術つかい) that captures actual outdoor field training methodologies. It documents practical physical instructions in stone castle wall scaling, active forest brush concealment, ground-hiding camouflage techniques (Uzuragakure style), and defensive structural ceiling infiltration tactics. Furthermore, two specific images on the page layout depict Fujita Seiko personally demonstrating close-quarters taijutsu martial arts compliance holds on his trainees.

Further back in the main text block on pages 132 to 138, the issue transitions into an extensive transcript block titled “Zadankai: Ninjutsu Chin-Mondo” (座談会 忍術珍問答 / “Roundtable Discussion: Rare Ninjutsu Questions and Answers”). This 7-page script-style text documents a deep-dive interview session where participating cartoonists query the grandmaster on authentic ninja history and historical espionage tactics.
