Jinin has a dark coloured beard and hair which he ties into a topknot. The remainder of his face appears to be rather angular and features a very protuberant nose. He wears a dark coloured poncho cloth over a standard Swordsman attire, consisting of a sleeveless dark shirt and matching pants along with a waist-guard, pin-striped arm and leg-warmers typical of his village and Kirigakure's forehead protector. He also has bandages around his neck like all the members of the previous generation of swordsmen.
As one of the Seven Ninja Swordsmen of the Mist, Jinin was one of the most powerful shinobi produced within Kirigakure.
Jinin signature weapon was the Kabutowari, a blunt sword that consists of a single sided axe and a hammer joined by a leather strap, which is said to be capable of breaking through any defence. This is achieved by first striking with the axe, before hammering it through the remainder of the obstruction with the hammer, resulting in the axe functioning much like a wedge.
