## Population density

Japan is 92 times more densely populated than Australia — 326 against 4 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 Australian dollar and the Japanese yen.
- Australia spans 5 time zones, so "local time" there is not a single answer.
- Different continents — Oceania and Asia.

## Australia

The sixth-largest country in the world and the only one that covers an entire continent. The Great Barrier Reef runs about 2,300 km and is the largest structure made by living organisms on Earth, visible from orbit. Around eighty percent of its mammals, reptiles and flowering plants exist nowhere else. Melbourne and Sydney are within roughly a hundred thousand people of each other, and which counts as the largest city depends on where the boundary is drawn.

## 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.
