From a review: "
The parlous state of Japan's pension system is well known, but Matsutani reviews the projections: by 2030, contributions will cover only 44% of expenditure, leaving a projected yearly deficit of ¥57 trillion by 2030 and a cumulative debt load of ¥1,240 trillion, roughly equal to the sum of all household wealth in Japan today. Getting back to balance would entail either more than doubling contributions from 15% to 34%, or cutting benefits by 56%."
