Travel To Japan & Reading Recommendations

I will be going to Japan for a couple of weeks and was talking to a friend about the Japanese far right movement taking a page from MAGA, of course. It made me wonder about Japan's trajectory as an axis member during WWII, committing atrocities in Asia to being nuked by the US, and now the number one holder of US treasuries. It's a fascinating history to me but also realize I have big holes in my understanding of Japan, how did this all happen? Was there a Japanese denazification after WWII or was it about as effective as it was in Germany?

If anyone has any good insightful reads about Japan and also any travel tips, I appreciate you!
