Shintai is a word used in Shinto to refer to an object that a kami resides in.
Examples include
A yorishiro is something which is invited to have a kami enter but does not yet have one in it.
In recent times a 700 year old tree was going to be cut down for a rail line. The people protested because they believed a kami lived inside it. So the city built a train station around it.
