This is a very competent and well-researched biographical history of General Douglas MacArthur and Emperor Hirohito, who between them largely defined the U.S. post-war occupation of Japan. The book not only tells their story but also that of the events that shaped them. A lot of research has been put into this, and the detail is totally compelling.
One niggle is that the exploits of the larger-than-life MacArthur are already well known, whereas Hirohito was a rather colourless and ineffectual individual. In short, there’s not much more to say about the one, and not much worth saying about the other. To my mind the comparison between the two men does come over as a forced attempt to generate interest.
Where the book really comes alive is in its treatment of social and political history. The American side is very interesting and informative. The Japanese part, a subject most English-speaking readers will be unfamiliar with, is even better.
