Books
Contemporary Japan: History, Politics, and Social Change Since The 1980s by Jeff Kingston The book has a great section on the modern yakuza and references to them in the text. The book wasn’t a critical hit but I think it is very good. The section on the nuclear industry was highly prescient.
The Japanese Mafia: Yakuza, Law and the State by Peter Hill. A seminal work on the growth of the yakuza over time and their political and social influence. A little out of date but one of the finest reference books available in English. Includes an interview with the number two of the Yamaguchi-gumi, Mr. Kiyoshi Takayama.
