If you're into gritty, raw memoirs like 'Yakuza Moon' that dive deep into the underbelly of Japanese society, you might want to check out 'Tokyo Vice' by Jake Adelstein. It's a gripping firsthand account of a journalist's time covering the yakuza, full of danger and dark revelations. Another great pick is 'Confessions of a Yakuza' by Junichi Saga, which offers an intimate look at the life of a gangster through interviews. Both books share that unflinching honesty and emotional weight that made 'Yakuza Moon' so compelling.
For something with a slightly different flavor but still in the same vein, 'The Buddha and the Borderline' by Kiera Van Gelder explores personal turmoil and redemption, though from a mental health perspective. It’s not about the yakuza, but the raw, confessional style might resonate with fans of Shoko Tendo’s work. I love how these books don’t shy away from the ugly truths, and they’ve all stayed with me long after reading.
