The current research examined age differences in self-esteem in Japan from young adults aged 20 to the elderly aged 69 with a focus on self-esteem trajectories from middle age to old age. Previous research in European American cultures has indicated that self-esteem rises from young adulthood into middle age, and sharply declines starting in one’s 50s or 60s. However, it was unclear whether this sharp drop would be found in Japan. Therefore, the present research investigated whether the same age differences were present in Japan by analyzing data from a large and diverse sample. Results showed that self-esteem increases from young adulthood into middle age, consistent with previous research. However, the sharp decline after the age of 50 was not found, which is different from the pattern in European American cultures. This may be related to a finding that people in East Asian cultures show more humble attitudes toward themselves.
