I've been really interested in Japanese culture for a few years now and read this book in preparation for a trip there soon. It provides some interesting historical context (Yamato court, Nara period, Heian period, Feudalism) before going deep into modern geopolitics (Meiji restoration, Pacific war, post-war prosperity).
One of the most interesting things I didn't know was how much Japanese culture has changed due to external influence (Chinese alphabet, Buddhism, Christianity, Confucianism, US-written Constitution). It's strange because of how often Japan is viewed as isolationist.
One criticism was how deep this book went on the post-war economics. It definitely felt like an important inflection point but might have been presented better with more graphs as opposed to written figures.
