Live side-by-side comparison of government debt. Japan currently owes about 56.0× more — a gap of $10.06 trillion. Updated every second from IMF baselines.
By total government debt, Ukraine ranks 42nd-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 Japan is roughly 19.6× that in Ukraine ($82,632 vs $4,210 per person).
Both countries carry debt-to-GDP ratios above the 100% mark that analysts often treat as an informal threshold for closer scrutiny — Ukraine at 110% and Japan at 230% — meaning each owes more than a full year's worth of national output.
The gap between them is widening: Japan's debt is growing faster in dollar terms ($4K/sec vs $1K/sec for Ukraine), adding roughly $253,152,000 to the difference each day.
Scale is part of the story too: Japan's population (124M) is about 2.9× Ukraine's (44M), 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.
