🇯🇵 Japan vs 🇰🇲 Comoros

Live side-by-side comparison of government debt. Japan currently owes about 15265.7× as much as the Comoros — 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, Japan ranks 1st by debt-to-GDP and the Comoros 156th. Measured per person, Japan is 3rd and the Comoros 167th.

Analysis

By total government debt, Japan ranks 3rd and the Comoros 182nd 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 115.7× that in the Comoros ($71,124 vs $615 per person).

The debt-to-GDP picture is asymmetric here: Japan sits at 205% of GDP, well above the Comoros' 31%, 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 the Comoros. Japan spends about 0.5% of government revenue on net interest ($8.8 billion in 2025), and the Comoros about 1.7% ($5 million in 2025). The Comoros 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: the Comoros' debt is growing faster in dollar terms ($3/sec vs −$15K/sec for Japan), closing the difference by roughly $1,265,846,400 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 131.9× the Comoros' (1M), 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.
