Jinenkan
Jinenkan is a traditional Japanese martial arts organization founded in 1996 by Fumio Manaka, a former senior student of Masaaki Hatsumi. The school is dedicated to preserving the classical techniques (koryū) of samurai and ninja lineages in their most authentic form. Emphasizing precision, structure, and historical integrity, Jinenkan teaches taijutsu (unarmed techniques), weapons, and battlefield tactics through a highly disciplined and research-based curriculum. Students are encouraged to train deeply, not for sport or combat, but for mastery and cultural preservation.
