Haruko and Theodore Cook, Japan at War: An Oral History

Also from a few months ago - this book was recommended to me by a professor of mine.  The book is centered around interviews with Japanese veterans of WWII, concerning their war-time experiences.  Begins to explain why Japanese soldiers treated Chinese civilians so horribly, touches upon material conditions under Japanese colonial regimes in places like Thailand or The Philippines, discusses the experiences of those involved in war-time medical experiments, etc. etc.
