Side by side

Population density

Japan is 2.8 times more densely populated than Poland — 326 against 117 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, Poland on the right.
• Different currencies: the Japanese yen and the Polish złoty.
• 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.

Poland

The Wieliczka salt mine near Kraków has been worked since the 13th century and holds chapels, chandeliers and statues carved entirely from rock salt, about 300 m down. Białowieża on the Belarusian border is the last large fragment of the primeval forest that once covered the European plain.

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.
