The assassination of Shinzo Abe last July sent shockwaves throughout Japan, and observers are still trying to make sense of how the country’s longest-serving prime minister met such a bloody end.

But the world of Japanese political literature moves quickly, and a new posthumous work plainly titled “Shinzo Abe: A Memoir” hit shelves this month. Currently available only in Japanese, the bestseller is based on roughly 36 hours of interviews that Abe completed with three Yomiuri Shimbun journalists, resulting in 440 pages of revelations.
