If you're looking for books on the subject of organised crime in Japan, it's hard to recommend anything. Maybe this one: https://www.goodreads.com/book/show/762585.Yakuza https://www.goodreads.com/book/show/762585.Yakuza To get a grasp of the darker sides of modern Japan, I wholly recommend these two books: https://www.goodreads.com/book/show/254259.Japan https://www.goodreads.com/book/show/254259.Japan and https://www.goodreads.com/book/show/93803.Dogs_and_Demons https://www.goodreads.com/book/show/93803.Dogs_and_Demons Both are real eye openers. The first is a must-read and very good overview. The latter concentrates on post-WW2's construction state but don't be repelled by that, because the construction sector is what is at the base of Japan's current problems. For a more scholarly but dryer take, the end-all book for people who want to know what's behind the curtain in Japanese society is this (I really enjoyed it but it's a long read): https://www.goodreads.com/book/show/274912.The_Enigma_of_Japanese_Power?ac=1&from_search=true&qid=ggHRwPOfqJ&rank=1 https://www.goodreads.com/book/show/274912.The_Enigma_of_Jap...
