Sarutobi Sasuke is a ninja who appears in kōdan narrative art and fictional writings. The nickname is generally believed to have been concocted from Meiji to the Taishou period. Some argue he is based on real live personages, such as Kōzuki Sasuke (上月佐助, Kōzuki Sasuke) and Sarutobi Nisuke (猿飛仁助, Sarutobi Nisuke).
