Hi there. Hatori Hanzo is probably the most famous ninja in Japanese history. He was from the Iga region, which is famous for its ninja schools (Miyamoto Musashi's famous yamabushi adversary, the one who was an expert at kusarigama jutsu, was from this region, and the famous ninja Momochi Sandayu as well). Hanzo was one of the very few ninja to escape massacre by Oda Nobunaga (for those who're not familiar with Japanese history, here's what happened: after a long period of wars between top japanese daimyos, Oda finally managed to unified Japan shortly after his main challenger, Takeda Shingen, died. Oda had used ninja on numerous occasions, but once victory was finally his, he started seeing the ninja more as a potentially very dangerous community and had them all slaughtered.). Oda didn't have time to enjoy his supremacy and at last make shogun: he was assassinated in revenge by a ninja sent by Hatori Hanzo (or maybe by Hanzo himself). The one who finally made shogun instead was one of Oda's generals, Tokugawa Ieyasu.
