Population density

Japan is 2.4 times more densely populated than Czechia — 326 against 138 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 — Czechia on the right, Japan on the left.
  • Different currencies: the Czech koruna and the Japanese yen.
  • Different continents — Europe and Asia.

Czechia

Landlocked and ringed by low mountains, so almost every river flows outward — the Elbe to the North Sea, the Oder to the Baltic, the Morava to the Black Sea. Czechia drinks more beer per head than any other country, and Pilsner Urquell in 1842 was the first pale lager.

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.
