This paper deals with suicide attempts with manifest suicidal intention in Kamakura, a suburban city near Tokyo with a population of about 100,000. In the first study 21 suicidal males and 23 suicidal females were compared with 50 applicants for the Japan Air Academy and 50 nurses at Jikei Medical School. The author concluded the immediate cause of suicide is the perceived meaning of the situation by the actor, and the perception of meaning is determined by the interaction with social structure.
