So much for the real temples. Here we have the headquarters of the Tenri sect, a syncretic folk religion that arose after WWII. Located somewhere around Nara, the precincts are very large and spacious, and feature Soviet-style dorms for the visiting faithful. My notes from the pictures indicate "the architecture is notable only for its scale...a mix of Shinto tradition, Buddhist influence, & concrete."
You can go in the main hall, but not up to the altar. Believers (BIG ones) are stationed everywhere and photos are forbidden. The remains of the founder, a woman, are kept in a special pit of some sort in the center of the main hall (you're not allowed to go near) and every day the priests go down and either offer her lunch, or eat lunch with her--it wasn't clear.
