🇿🇦 South Africa vs 🇯🇵 Japan

Analysis

By total government debt, South Africa ranks 29th-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 12.3× that in South Africa ($72,683 vs $5,900 per person).

The debt-to-GDP picture is asymmetric here: Japan sits at 207% of GDP, well above South Africa's 79%, 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 gap between them is narrowing: South Africa's debt is growing faster in dollar terms ($1K/sec vs $-6676/sec for Japan), closing the difference by roughly $694,137,600 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 a rough 34 years.

Scale is part of the story too: Japan's population (124M) is about 2.0× South Africa's (62M), 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.
