Is there such thing as Korean ninjas?

Answer 1

Actually ; no their isn't a such thing as Ninja in Korea. Ninja were people whom simply started out as farmers whom used several Martial Arts weapons that we know today as farm tools due to the fact that while under various Japanese Emperor rule, citizens weren't allowed to have things that were classified as an obvious weapon. (Sword,Archery bow,etc). These farmers taught themselves how to use these farm tools that they developed into martial arts weapons as we similarly use them today. Such as the Nunchaku was possibly used as a rice flail and in some instances a horse bridal.And the Kama was used to harvest the rice as a slicing tool. Anyway, once these farmers developed all of these techniques they would then fight the Japanese emperor's band of Samurai warriors that were the Imperial Japan's version of Sheriff/Police and Bounty Hunters.

Most cases these Samurai were crooked soldiers doing what their emperor wished for them to do and most of the time it was either to collect tax or ravage villages by commiting murder,burning down villages and stealing anything of value (At least prior to the Edo era). Eventually these Japanese emperors were noticing the virtual unstoppable nature of these farmers and recruited them as what we know now as Ninja.Or known as Shinobi. Which loosely translates to "Covert Agent" or "Mercenary".Ninja were used by emperors for infiltrating enemy territory for assassinations, stealing,or just gathering information. Things that the Samurai wasn't believed to be properly trained for in contrast to the nature of the Ninja. The bottom line being, the Ninja originated in Japan.Their is no historical evidence what so ever to support the idea that Korea ever had what was known as the Shinobi or Ninja at least as Japan knew it to be. I'm certain that Korean military of that time period had special operatives that did certain missions, but they weren't Shinobi or Ninja like in Japan.
