In this study, we examine an income replacement rate of each prefecture in Japanese public pension system using an agent-based simulation. The income replacement rate is a ratio of an individual's pension and the average income. On the basis of the statistics of each prefecture, we calculate the amount of pension, wage structure and marriage behavior using a proposed agent-based model. From simulation results, we try to see circumstances of current pensioners in each prefecture based on the population change, the income replacement rate and the wage growth rate. We visualize differences of income replacement rates among 47 prefectures for pensioners to see the value of their pension benefit by comparing to the average income in each prefecture. The proposed method helps pensioners to design their lives with pension benefits.
