Found across kōdan narrative art and fictional writings in Japanese folklore, Sarutobi Sasuke is a legendary ninja commonly depicted as the leader of the Sanada Ten Braves, a fictional group of ten ninjas who supposedly assisted warlord Sanada Yukimura during the Siege of Osaka.

Although he’s just a young boy, Sasuke has been blessed with extraordinary abilities like shape-shifting and superhuman strength. In fact, Sarutobi Sasuke’s very name means "monkey jump" in Japanese, a nod to his agility and quickness in arboreal landscapes.

While there’s no evidence to prove his existence or involvement in the Siege of Osaka, Sasuke's impact on ninja fiction is undeniable. Today, Sarutobi Sasuke's legacy continues to thrive in popular franchises like "Naruto," where his name resonates through characters such as Sasuke Uchiha.
