The purpose of this study was to clarify the following two questions. One was to know the age when the idea of death occurred spontaneously when recalling the future, and the other was to know the characteristics of the age by comparing the anxiety of death and the attitude toward death using a cross-sectional method. The subjects of the study were 117 adolescents, 142 middle-aged, and 202 elderly. The data were collected in a questionnaire survey, and the subjects answered about bereavement experience, depression, the anxiety of death, and the attitude toward death. In addition, we asked for a free description of the recollection of the future and examined it using content analysis. Attitudes toward death were evaluated using the DAP (Death Attitude Profile) scale and confirmed to have a four-factor structure of "Fear of Death" factor, "Escape Oriented Death Acceptance" factor, "Approach-Oriented Death Acceptance" factor, and "Neutral Death Acceptance" factor. Data on the anxiety of death and the attitude toward death were examined using a two factor analysis of variance with age group x gender, age group x bereavement experience, and age group x depression as independent variables. As a result, it was shown that the idea of death spontaneously appeared from almost old age. Anxiety of death and "Fear of Death" factors were higher in the adolescent group than in other age groups. "Escape-Oriented Death Acceptance" factor, "Approach-Oriented Death Acceptance" factor, and "Neutral Death Acceptance" factor were higher in the elderly group than in other age groups. These results were similar to those in previous studies. In the content analysis, the following six categories were obtained for the contents of the future recall, which are common to all age groups.
