🇺🇸 United States vs 🇯🇵 Japan

Analysis

By total government debt, United States ranks 1st-largest and Japan ranks 3rd-largest among the 137 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 national debt in United States is roughly 1.6× that in Japan ($119,351 vs $72,710 per person).

Both countries carry debt-to-GDP ratios above the 100% mark that analysts often treat as an informal threshold for closer scrutiny — United States at 124% and Japan at 207% — meaning each owes more than a full year's worth of national output.

The gap between them is widening: United States's debt is growing faster in dollar terms ($60K/sec vs $-6676/sec for Japan), adding roughly $5,778,086,400 to the difference each day.

Scale is part of the story too: United States's population (336M) is about 2.7× Japan's (124M), 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.
