During World War II, many of Japans soldiers committed such crimes against humanity that the world recoiled in horror. During the notorious six-week-long rape of Nanking in 1937, Japanese forces murdered at least 200,000 men, women, and children. Throughout the Pacific War, Allied prisoners were often starved, tortured, beheaded, even cannibalized. Although Japans military men fought bravely against outnumbering forces again and again, their astonishing brutality made them a loathsome, unforgivable enemy. While this chapter of Japanese history is well known, few realize that earlier in this century the Japanese were celebrated throughout the West for their chivalry in warfare. During the Boxer Rebellion in China and the savage Russo-Japanese War of 1904-5, the Western Press lauded the Japanese for their kindness to the wounded and imprisoned enemy. Warriors of the Rising Sun chronicles the Japanese militarys transformation from honorable knights of Bushido into men who massacred thousands during the Pacific War. Crucial in bringing about this change was Western rejection of Japan as an aspiring colonial power, as well as the Wests racist, anti-Japanese immigration policies. Japans leaders chose military brutality as a necessary means to achieve a rightful place in the world. Today, Japan has the second largest military budget in the world. What lessons have her leaders learned from the past wars?
