Wow!  I hope you find true information. Japanese without sacraments for 250 years and were able to maintain the faith by 65%. How Nagawski and Hiroshama cities were destroyed by atomic bombs on predominant catholics. How it was experimental by the secret societies, and how Japan surrendered before the bombs and the Pope who knew of this surrender.

A Very interesting subject. I just happen to have 3 books written by so called doctors and scientists on the aftermath of these bombs on the people.  It is demonic. No sadness, just how the effects of the bombs were on children, women, pregnancies and such. The way it is written is demonic, ugly.  I found the books at an estate sale decades ago. I have read them at least 3 times, just to keep me awakened to the ugliness, that it is not my imagination that I read what I read.

Oh, books on the monks, Father Maximillan Kolbe, their group was in the area of the bomb and all survived.

Be wary of Shusaku Endo's oeuvre–Novus Ordo and so admired by Martin Scorcese of Last Temptation infamy that Scorcese put Endo's Silence to film. He raised Japanese Catholic hackles for his portrayal of Catholic avoiding marytyrdom by stepping on images of Jesus and Mary.
