Chōjūrō (長十郎, Chōjūrō) is one of Kirigakure's Seven Ninja Swordsmen of the Mist.
Chōjūrō has short, tufty blue hair, and dark eyes. He also has pointed, shark-like teeth; a common trait of the members of the Seven Ninja Swordsmen of the Mist as well as apprentices share. He wears square, black-rimmed glasses connected to ear protectors, a blue pin-striped shirt and camouflage pattern pants. Also, he wears his forehead protector on the front of his holster which he uses to carry Hiramekarei. The sword itself is wrapped in bandages leaving only the double hilt visible. He also has shuriken holsters strapped onto each of his legs.
