The ninjas were people who served daimyos (feudal lords) during the Sengoku Period (1493-1573), whose missions included sneaking into the enemy’s camp, conducting espionage, and assassinations. They are also known as shinobi no mono (sneaking person). They were famous for their legendary skills such as igaryu (iga style) and kogaryu (koka style). They used ninjutsu (ninja skills) with tricks such as gosha no jutsu (five wheels technique) by which they gained control over someone’s mind, katon no jutsu (fire release technique) which involved using gun powder to lay down a smoke screen, and henso jutsu (disguise techniques) that meant disguising oneself as a merchant or monk.
