Side by side

Population density

Japan is 1.7 times more densely populated than Italy — 326 against 196 people per km². Density is where area and population interact, and it often reverses the impression the headline figures give — a large country with a small population can feel emptier than a small crowded one by an enormous margin.

Practical differences

• They drive on opposite sides — Italy on the right, Japan on the left.
• Different currencies: the Euro and the Japanese yen.
• Different continents — Europe and Asia.

Italy

Italy has three of Europe's most active volcanoes — Etna, Stromboli and Vesuvius — and Stromboli has been erupting more or less continuously for at least 2,000 years. It has more UNESCO World Heritage sites than any other country. The Alps and Apennines mean about three-quarters of the land is mountain or hill.

Japan

A 2023 government survey using digital mapping counted 14,125 islands, more than double the long-quoted figure of 6,852. About three-quarters of the land is mountain, so nearly everyone lives on a narrow band of coastal plain. Japan sits where four tectonic plates meet and records a fifth of the world's magnitude-6-and-above earthquakes.

Neutral facts only. Nothing here addresses politics, government, economics or which country is preferable in any respect — population is the one figure that dates, and it carries its year.
