I just wanted to take the time to suggest the book Sacred Science of Ancient Japan: Lost Chronicles of the Gods by Avery Marrow. It is a very intrigueing look into Japanese parahistory and the mysterious tales of how some of this knowledge was brought to light. Avery Marrow does a good job of not shoving facts and beliefs down your throat. Instead, he shows you the information and lets you draw your own opinion from it. Its an excellent read for anyone into history's mysteries and/or Japanese culture.
I would also like to see what books any of y'all might want to suggest. I'm always searching for more books.
