To the Editor.
—The review by Dr Perlmutter1 of my book, Encounters With Aging: Mythologies of Menopause in Japan and North America, has so many factual errors in it that I must set the record straight.I did not "interview more than 100 Japanese women over 20 years" or make use for comparative purposes of "published reports or material that had already been gathered and that had utilized other instruments." In fact, a questionnaire was distributed to over 1300 Japanese women, and I interviewed 105 of those same women over the course of 1 year. Contrary to what Perlmutter says, the questionnaire was exactly the same— apart from necessary cultural modifications—as the one used for large samples of Massachussetts and Manitoban women by my colleagues Drs Sonja McKinlay and Patricia Kaufert, respectively, with whom I worked closely at all stages of the survey research. As stated in my book,
