This study draws on data from interviews with individuals aged 65 to 86 (n = 20) to examine the developmental pathways of identity formed from adolescence to seniority and to especially investigate elderly identity. The main findings were as follows. In adolescence, we did not find "identity achievement". Identity achievement was found to occur after adolescence in this study. The theme of a young adult's identity was how to commit to a new role. If they had not sought out and committed to their own course in adolescence, they were almost at the same status of identity achievement as that of a young adult after having strove for a new role. In the elderly, changes in identity due to the loss of the familiar, occupation, and health and the regret that they did not seek out and commit to their own course in adolescence. In addition, aging and death were structural factors for identity in the elderly, which were distinguished from the awareness of physical and social changes that occurs during middle age.
