Togashi is easily recognizable by his schoolcap, which is a memento from his brother, and the scar over his left eye, which is never explained. He also has long, disheveled black hair and a pencil mustache. He wears a standard Otokojuku uniform, rarely buttoned up, and in the anime it is depicted as black. He usually wears bandages on his wrists and waist, which he tucks his knife into.

He appears more professional in Sora Yori Takaku, wearing a suit with his hair shorter and combed back.
