The author made a study, with the cooperation of the police, of 27 cases of dying together that occurred during the year 1977. When findings of the study were compared with those of similar studies conducted in the United States, England and Wales, it was indicated that the parent-child relationship was stronger in Japan. However, the relationship between husband and wife or between lovers may be stronger in the United States and England and Wales. It may be said that the strength of the family relationship in England and Wales falls somewhere between that in the United States and that in Japan.
