The title Jonin is split into two separate categories. Before you are awarded the full title Jonin, you are, by appointment, a Special Jonin. This is the next rank up from Chunin and covers everything a Chunin does, but also includes high-risk missions between other countries, such as: escorting royalty. These missions are much more delicate and dangerous than previous missions. Complete Jonins are assigned to the most dangerous and highest paying missions. These missions can be anything from high-level inter-nation assassinations to delivering and collecting important documents and treaties. Only a ninja with a wealth of combat experience can become a full Jonin. At some point in a Jonin's career he or she will be assigned a team of Genin to teach and guide their development. This responsibility is huge as they will oversee their students training and be responsible for their lives until they are Chunin. 
The ANBU is not exactly a rank of a ninja. The ANBU operates as top-level assassins, interrogators, and also hunters of ninja who, for whatever reason, have defected from their village. They are a secretive organization that exists in every village and are under the direct orders of their Kage. Life expectancy for ANBU members is very short as they have the most dangerous assignments; they wear animal masks (representing the animals of the Zodiac) to protect their identity and to further induce fear into their targets. ANBU members also have a tattoo on their shoulder. 
The Sannin is the name of three ninjas with with immense skill. Many times they are as powerful, if not more powerful, than Kages. They usually live away from the village to keep a low profile but are forced to keep in touch with the village every now and then for safety measures.

In order to become a Kage, they have to climb the proverbial "ladder" from the Genin rank. Kages are responsible for the protection and well being of their people and all the important the decision making falls on their shoulders. There is a council of elders that they often consult for high-level decisions, but ultimately, the Kage has the final say. A new Kage is hand picked and groomed by the current Kage to take their place.
