Shinto sects and schools

Shinto (神道, shintō), the folk religion of Japan, developed a diversity of schools and sects, outbranching from the original Ko-Shintō (ancient Shintō) since Buddhism was introduced into Japan in the sixth century.

This may be because of their small size and influence, fairly unknown presence or practices, or because those schools are new branches from older schools and still considered within their structure.
