New in paperback. Hardcover was published in 2012. This is the first book in English to examine the radical changes that took place in Japanese ideas about sex, romance and male-female relations in the wake of Japan's defeat and occupation by Allied forces at the end of the Second World War. It is based on extensive archival research into popular magazines and newspapers as well as a range of sexological publications including sex guides, reports and manuals published during the Occupation and immediately after.
