Samurai Secrets: 1888 Martial Arts Manual for Cops Revealed

A newly translated 19th-century book, written by samurai, describes martial arts techniques designed to help police officers of the time. The book, which contains illustrated instructions, was published in 1888, a time when the samurai class had lost many of its privileges and the formally secretive martial art schools that taught the samurai were willing to divulge their secrets. This book drew on the expertise of 16 martial arts schools operating in Japan in 1888.
