This book will set the terms of debate over the future of Japanese corporate governance for the next several years. It is a fine contribution to discussions in comparative political economy about models of institutional change and how to link them to the dynamics we observe on the ground. Although the price of this weighty hardback will give readers pause, it is an enormously valuable compendium which no serious library can do without. The authors have different views of how their pieces of the elephant of Japanese corporate governance fit with the others; these discussions echo those that have raged over the past several years in institutionalist political economy. The volume takes a big tent approach—reflecting these tensions rather than resolving them—but the airing of the debate among these experts is one from which readers will learn much. Several of the pieces are empirical gems on their own. Christina Ahmadjian's chapter is a nuanced examination of the mechanisms through which the increase in foreign shareholdings has challenged the traditional modes of corporate governance, as well as the limits to that influence. Zenichi Shishido's chapter on the vast legal changes in the commercial code and the eventual adoption of corporate law uses legal changes to reflect on the political pressures behind the changing standard model of Japanese corporate governance, which we once called the J-model. Hideaki Miyajima explores the causes and performance effects of corporate governance changes at the company level, showing that not all changes are equal. Greater information disclosure has significant consequences for performance, but minority shareholder protection and board reforms that bring in outsiders do not. Ronald Dore uses survey material from several sources, including an original one of his own, to assess the extent to which managerial views of the relative importance of shareholders and employees have evolved since the 1990s. One could certainly cite others. Scholars of corporate finance, law, management and social science will each find chapters from which they could learn with profit. The book is simply too empirically rich for a reviewer to summarize.
