Zatoichi

Ichi is a lone goze (blind woman singer) who has become separated from her traveling entertainment troupe. Wondering how she will find her place in life, she carries only a shamisen (a traditional Japanese stringed instrument) and a walking stick with a hidden blade inside. When necessary, she uses her exceptional sword skills to fight off yakuza and other villains.

The series follows the adventures of Sabu, a young Edo bakufu investigator traveling with the blind master swordsman Ichi. In their travels, they assist the common people in solving mysteries and righting wrongs (usually committed by bandits or corrupt officials). Sabu is engaged to Midori, the daughter of his boss, who works as a police officer for the Tokugawa shogunate. (Source: Wikipedia)
