How is Buddhism structured? All I really know if you have lay people, priests, monks, and in some places masters or grand masters (I don't know if these are the same), and there are various different variants of the religion, each with their own clergy etc..
So, by analogy, Britain has the arch bishop of Canterbury, and he's the principle "head of the Church" of England. What equivalent formal positions exist in Japanese Buddhism?
Google wasn't much help! All I found out was that e.g. Soto zen has two principle temples, Eihei-ji and Sōji-ji. Do they have heads? Soto's - democratic - head is the "Shūmusōchō"; where can I read about this position?
Are the other subsets of Buddhism structured similarly?
