This rich collection of essays puts flesh on the tired bones of Japanese debates about whether to protect or revise the 1947 Constitution. Highlighting civic activism across the postwar period, the authors show the contention to be much more complicated—and politically and socially dynamic—than an either/or proposition. Comparisons with Taiwan and South Korea and attention not only to Article 9 but to human rights and environmental questions give the book an expansive character. This intelligent and informative study is a pleasure to read.
