Jōnin (上忍, Jōnin; lit. meaning "High Ninja", Meaning (Viz) "Elite Ninja") are generally highly-experienced shinobi with great individual skill who serve as military captains. They are often sent on A-rank missions, and experienced jōnin may even be sent on S-rank missions (which are considered to be the greatest difficulty). It is not unusual for jōnin to go on missions alone. Jōnin are generally able to use at least two types of elemental chakra, proficient genjutsu, and decent taijutsu skills.
The villagers may send their recommendations for a jōnin appointment. The Kage reads said recommendations and may consider appointing an individual a jōnin if his or her qualities are recognised as adequate by enough people and by himself/herself. However, there was mention of a Jōnin Exam in the anime's Yakumo Kurama Rescue Mission. When a ninja becomes a jōnin, they may be assigned a three-man genin team to supervise, with their duty being to help instruct and train these genin to become competent ninja. They train these ninja for quite a while and lead missions with them. They can also decide when the genin are ready to join in the Chūnin Exams. In Konohagakure, it is up to the jōnin to decide whether a candidate Hokage would be given the position permanently. They also have a special rank known as Jōnin Commander. Shinobi who have jōnin-level skills only in a specialised area are classified as Tokubetsu Jōnin.
