Side by side

Population density

Japan is 5.1 times more densely populated than Ukraine — 326 against 65 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 — Japan on the left, Ukraine on the right.
• Different currencies: the Japanese yen and the Ukrainian hryvnia.
• Different continents — Asia and Europe.

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.

Ukraine

The largest country entirely within Europe. About a quarter of the world's chernozem — the deep black soil that makes grain farming so productive — lies here. The Carpathians in the west reach 2,061 m, and the rest of the country is largely steppe drained by the Dnieper.

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.
