Analysis

By total government debt, Japan ranks 3rd and São Tomé and Príncipe 180th among the 194 sovereigns tracked on this site.

On a per-citizen basis the picture can look different from the nominal totals: a resident's notional share of the government debt in Japan is roughly 27.5× that in São Tomé and Príncipe ($71,124 vs $2,588 per person).

The debt-to-GDP picture is asymmetric here: Japan sits at 205% of GDP, well above São Tomé and Príncipe's 59%, meaning Japan owes far more relative to the size of its own economy — even where the nominal, dollar-for-dollar comparison above suggests otherwise.

The IMF puts Japan at 132% of GDP net of financial assets, and publishes no net debt figure for São Tomé and Príncipe. Japan spends about 0.5% of government revenue on net interest ($8.8 billion in 2025), and São Tomé and Príncipe about 3.1% ($6 million in 2025). São Tomé and Príncipe carries the lower debt ratio but the heavier interest bill: rates, currency and assets matter as well as the size of the debt. See the full interest ranking.

The gap between them is narrowing: São Tomé and Príncipe's debt is growing faster in dollar terms ($2/sec vs −$15K/sec for Japan), closing the difference by roughly $1,265,760,000 per day. At that pace — and holding both growth rates constant, a simplification, since real-world rates shift with fiscal policy — the two would reach a similar total in roughly 19 years.

Scale is part of the story too: Japan's population (123M) is about 500.7× São Tomé and Príncipe's (0M), which is part of why the nominal and per-capita comparisons above can point in different directions — a government's debt load scales loosely with the size of both its economy and its population, not either alone.
