I just started studying Shinto today, so I have my textbook open....my book says it's practices in large scale in shrines and Japanese homes have small shrines in them for daily practice. It includes aspects of animism (everything has spirit, rocks, trees, mountains...) and ancestor veneration. There are three forms of Shinto: State Shinto which is known as Jinja (shrine), Sectarian Shinto which splintered off from State Shinto to practice the religious side of Shinto as opposed to the state directed aspects, and Domestic Shinto, the basic and common form which takes place in many Japanese homes.
That's as far as I got in the chapter, sorry.
