Regarded as the 14th and final heir to the Kōga-ryū Wada-ha Ninjutsu tradition, he was highly respected by his peers and a core member of Japan's classical martial arts community. Biography. Isamu Fujita was born in Tokyo, and studied Kōga-ryū Wada-ha (Ninjutsu) under the tutelage of his grandfather, Fujita Shintazaemon, 13th Soke of the Wada branch of Kōga-ryū Ninjutsu. He was educated at both Waseda and Meiji universities, and initially began his career at a newspaper company. He went on to study  several other martial arts and was also noted as an author, researcher and collector of ancient scrolls. According to some references, "opinions are divided if he was a real ninja or a mere budō researcher." During World War II, Fujita taught Koga Ryu Ninjutsu in the Army Academy of Nakano (Rikugun Nakano Gakkō). Fujita later worked as a government security specialist. In later years he was influential in teaching many traditional Japanese arts. Notable students include Motokatsu Inoue, Mabuni Kenwa, Fujitani Masatoshi, actor Tomisaburo Wakayama and Manzo Iwata, who became heir to some of his styles. Fujita left no heir  for Kōga-ryū Wada Ha. Seiko Fujita published "Zukai Torinawajutsu" showing hundreds of Hojōjutsu ties from many different schools, and several other texts on ninjutsu and martial arts. He died of cirrhosis of the liver at about the age of 68 and likely suffered from hereditary angioedema (which can preclude the practice of martial arts, although Fujita may have demonstrated the ability to overcome some disease symptoms). His collection, the "Fujita Seiko Bunko", is housed at Iga-Ueno Museum, Odawara Castle. Bibliography of the main works.
