🇯🇵 Japan vs 🇧🇳 Brunei

Live side-by-side comparison of government debt. Japan currently owes about 34968.8× as much as Brunei — 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 Brunei 193rd. Measured per person, Japan is 3rd and Brunei 172nd.

Analysis

By total government debt, Japan ranks 3rd and Brunei 186th 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 132.5× that in Brunei ($71,124 vs $537 per person).

The debt-to-GDP picture is asymmetric here: Japan sits at 205% of GDP, well above Brunei's 2%, 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 Brunei. Japan spends about 0.5% of government revenue on net interest ($8.8 billion in 2025), while Brunei takes in at least as much interest as it owes. See the full interest ranking.

The gap between them is narrowing: Brunei's debt is growing faster in dollar terms ($0.11/sec vs −$15K/sec for Japan), closing the difference by roughly $1,265,596,704 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 263.9× Brunei'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.

Japan and Brunei are both grouped under this site's “Asia-Pacific” region, so this is, in effect, an intra-regional comparison as well.
