## Population density

Japan is 20 times more densely populated than Argentina — 326 against 16 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 — Argentina on the right, Japan on the left.
- Different currencies: the Argentine peso and the Japanese yen.
- Different continents — South America and Asia.

## Argentina

The eighth-largest country in the world and the largest Spanish-speaking one. Aconcagua at 6,961 m is the highest mountain outside Asia; the Laguna del Carbón, about 1,000 km away, is 105 m below sea level and the lowest point in the western hemisphere. Ushuaia in Tierra del Fuego is the southernmost city of any size on Earth.

## 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.
