The reason has less to do with tepid growth or lackluster consumer spending. Rather, it’s Tokyo’s titanically large public debt and the fact that investors are increasingly concerned about it. “Japan is much closer to a debt crisis than people think,” argues economist Robin Brooks at the Brookings Institution.
Estimates of the true magnitude of Japan’s debt-to-gross domestic product ratio range from 240% to 260%. Either or anywhere in between means Japan has the biggest debt burden by a wide margin in the developed world.
