This paper explores the public pension claiming behavior of the Japanese. First, we perform financial simulations and estimate the expected utility, depicting the typical patterns of pension benefits in a lifecycle model. We show that the optimal retirement age depends on the beneficiaries' mortality risk, discount rate, initial wealth, and risk attitude. Second, we use individual-level data from the Japanese Study on Aging and Retirement to examine empirically the determinants of the take-up timing. We find supportive evidence that most of the factors examined in the simulation are indeed significantly associated with early claiming of pension benefits for wage earners.
