Side by side

Population density

Japan is 1.3 times more densely populated than Jamaica — 326 against 258 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

• Different currencies: the Jamaican dollar and the Japanese yen.
• Different continents — North America and Asia.

Jamaica

The Blue Mountains rise to 2,256 m within about 15 km of the coast, so the island is far steeper than its size suggests. Cockpit Country in the west is a karst landscape of conical hills and sinkholes, largely trackless, and holds most of Jamaica's endemic plants. The island is about 235 km long and 82 km at its widest.

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.
