About the book (from Goodreads):
Hirohito was dominated by a military power clique bent on conquest who in the 1930s virtually seized control of Japan. While the Japanese military excused or justified their acts in the name of the Emperor, Hirohito was rarely consulted, & it was not until 1945 that he finally stopped the war. Why did he remain silent? What was this man really like? Leonard Mosley clearly defines the role of Hirohito in WWII.
About Hirohito (from Wikipedia):
Hirohito (April 29, 1901 – January 7, 1989) was the 124th Emperor of Japan according to the traditional order of succession, reigning from December 25, 1926, until his death. He was succeeded by his eldest son, Akihito. In Japan, he is now referred to primarily by his posthumous name, Emperor Shōwa. The word Shōwa is the name of the era that corresponded with the Emperor’s reign, and was made the Emperor’s own name upon his death. The name Hirohito means “abundant benevolence”.
At the start of his reign, Japan was already one of the great powers—the ninth-largest economy in the world, the third-largest naval power, and one of the four permanent members of the council of the League of Nations. He was the head of state under the Constitution of the Empire of Japan during Japan’s imperial expansion, militarization, and involvement in World War II. After Japan’s surrender of the war, he was not prosecuted for war crimes as many other leading government figures were, and his degree of involvement in wartime decisions remains controversial among historians. During the post-war period, he became the symbol of the new state under the post-war constitution and Japan’s recovery, and by the end of his reign, Japan had emerged as the world’s second largest economy.
