Shrines may be cared for by priests, by local communities, or by families on whose property the shrine is found. Shinto priests are known in Japanese as "kannushi", meaning "proprietor of kami", or alternatively as "shinshoku" or "shinkan". Many kannushi take on the role in a line of hereditary succession traced down specific families. In contemporary Japan, there are two main training universities for those wishing to become kannushi, at Kokugakuin University in Tokyo and at Kogakkan University in Mie Prefecture. Priests can rise through the ranks over the course of their careers. The number of priests at a particular shrine can vary; some shrines can have over 12 priests, and others have none, instead being administered by local lay volunteers. Some priests earn a living administering to multiple small shrines, sometimes over ten or more.
