The image of the ninja remains strong today. In fact, ninja as popular culture icons were already popular in Japan in the era before World War II. During the 1960s, the Shinobi no mono films ignited a ninjutsu and ninja boom that spread widely overseas as part of a larger international fascination with martial arts. Today, there are instructors who are knowledgeable, and have read extensively, studied deeply, and trained diligently. Others, however, are merely pretenders who have failed to read extensively, study deeply, and train diligently. They are the Fools, Fakes, and Frauds of ninjutsuÑthe attention-seeking quick-buck scammers of the martial arts who want to claim the title of ninja or shinobi without having earned the right by having the knowledge or doing the hard work. This book was written to help you avoid them.
