The roots of the ninja were the "ninja", which existed from the Sengoku period to the Edo period in Japan. During the Warring States period, which lasted 150 years from the late 15th century, the sneak in was an intelligence agent active under a daimyo. The technique of sneaking is not only a fighting technique that is easily spotlighted, but also a technique for collecting information and building relationships. The teaching was to avoid unnecessary battles and move efficiently based on accurate information. It may be closer to the modern CIA agent or 007. Controlling information is the essence of a ninja. If you think so, even if you do not appear on the stage, you will deliver information to those who want it, analyze and manipulate information, support others with shadows, and move the world. Such a shinobi philosophy will surely lead to modern times.
