Live side-by-side comparison of government debt. Japan currently owes about 2509.7× as much as South Sudan — a gap of $8.72 trillion. Updated every second from each country's baseline figure; sources below.

Net debt and interest: IMF World Economic Outlook, October 2026, general government, 2025, mostly IMF estimates. A dash means no comparable figure. How these are calculated.

Among the 194 governments tracked here, South Sudan ranks 70th by debt-to-GDP and Japan 1st. Measured per person, South Sudan is 186th and Japan 3rd.

Analysis

By total government debt, South Sudan ranks 156th and Japan 3rd 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 254.5× that in South Sudan ($71,124 vs $280 per person).

The debt-to-GDP picture is asymmetric here: Japan sits at 205% of GDP, well above South Sudan's 64%, meaning Japan owes far more relative to the size of its own economy — even where the nominal, dollar-for-dollar comparison above suggests otherwise.

Net of financial assets: the IMF puts South Sudan at 64% of GDP and Japan at 132%, against 64% and 205% gross. South Sudan spends about 6.5% of government revenue on net interest ($77 million in 2025), and Japan about 0.5% ($8.8 billion in 2025). South Sudan 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: South Sudan's debt is growing faster in dollar terms (−$3/sec vs −$15K/sec for Japan), closing the difference by roughly $1,265,328,000 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 9.9× South Sudan's (12M), 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.
