title: Marriage and divorce over a century in Japan: social biomedicine, not yet societal therapy.
abstract: During the past half-century, the differences found in the spectral element of marriages vs. divorces in Tokyo reveal a half-year aspect which increasingly dominates in marriages, probably as a result of a mix of socio-economic, climatic and/or geomagnetic, as well as human affection-related factors, On the other hand, a decadal component is prominent in divorces, possibly in association with non-photic solar activity. Sparser (yearly, not monthly) records, obtained over a century at different latitudes in Japan, demonstrate that the decadal components are not consistent in moving spectra of original (as yet not detrended) data. Longer and denser series over much greater differences in latitudes and longitudes will have to be subjected to a much more thorough scrutiny, in conjunction with a series of possibly pertinent variables, to assess the contributions of different sources of variation in different areas of Japan and world wide, preferably in democratic, non-combatant areas, where the socio-economical, political and other war-associated conditions are mostly in the background.
