Ninjas were highly skilled in martial arts, stealth, and disguise. They were also experts in the use of various weapons, including swords, daggers, shuriken (throwing stars), and blowguns.
Ninjas were often seen as mysterious and even supernatural figures. This was due in part to the secrecy that surrounded their activities and the fact that they often wore black clothing and masks to conceal their identities.
Ninjas played an important role in Japanese history, and their legacy continues to fascinate people around the world. Today, ninjas are often depicted in popular culture, such as in movies, TV shows, and video games.
