Books about the Japanese Occult Boom (okarutobūmu)

I'm looking for books about the cultural phenomenon known as the Japanese Occult Boom (okarutobūmu) that occured during the 70s, 80s and to a lesser extent the 90s. I´m interested in both the in depth sociological studies about the phenomenon and/or any piece of fiction that takes place during said years. Any titles regarding the matter will be hugely apreciated!
