Anyone on this board ever heard of Kuroda Ninjutsu? Im my intermittent delving into old martial arts documents that get loaded from time to time unto google books I came across a curious reference to ‘Kuroda Ninjitsu’, after playing about with the spelling and time period settings (‘Ninjitsu’ rather than the ‘Ninjutsu’ was a common spelling post war) In the May 1964 issue of Blakbelt magazine (p.33) smack in the middle of the japan ninja boom and predating the appearance of Yoshiaki (Masaaki) Hatsumi’s appearance in blackbelt we have the curious reference of Kuroda Ninjitsu: Black Belt “Cummings studies have opened the door to a vast knowledge of Kobudo methods. He is familiar with a few Kobudo arts designated intangible cultural properties by the Japanse government e.g. Kuroda ninjitsu (an art of invisibility using camouflage techniques), Kusarigama (A sickle and chain weapon), and Yagyu ryu Tessenjutsu (The art of using an iron fan and developed by a family of kendo instructors to the Tokugawa shoguns)” Joseph Cummins seems to be one of the post war foreign martial arts practitioners that popularised the contact with japan. Serving in the US 549th Anti-Aircraft Artillery during WWII. He first learned western fencing under an Italian artillery Captain in 1947, and then took further Sabre lessons after returning to Italy under Maestro Atos Perone from 1953 till 1956. He then travelled to Japan in 1960 and studied under Kobudo Master Kempu Matsuo of the Shinken Kai in Yokohama, learning Muso-Ryu Jojutsu and then iaido, having reached 6th Dan by 1964 on account on his previous skill with the blade, as well as being introduced to the above mentioned techniques. Regardless of his background the mention of Kuroda Ryu is curious because it is: Not one of schools associated with the post war Ninjutsu expert claimants (Hatsumi, Takamatsu, Nawa, Iga-Hakuyusai, Seiko and Nina Consueto-Epsom’s own mysterious instructor) Not one of the ninjutsu ryu’s associated with the traditional family names from Iga and Koga (though I have not cross referenced against the Bugei Ryuha Daijiten ) Anyone ever heard of this Nijutsu Ryu before? Is it an Ninjutsu auxiliary art attached to a Koryu school like Katori Shinto Ryu? Anyone know what happened to Joseph Cummings?
