Using the latest data on the Japanese social security pension, we have explored a simulation model of its long-term financial balance. With a partial funding shift to a consumption-based tax, a moderate slimming-down of the future anticipated benefits will enable the contribution rate to stay at the level no higher than the current 17.35 percent. A partial replacement by a 4-percent private personal retirement account is also examined. Early-and delayed-retirement options are considered, too.
