Flag of Japan
The flag of Japan features a crimson-red circle at the center of a white field.
Where it is
Japan is grouped in Eastern Asia, within Roam’s Asia region. No land neighbours are listed in the source. The source classifies it as not landlocked.
Japan has a recorded area of 377,930 square kilometres. Among the 5 countries assigned to Eastern Asia in this dataset, it ranks 3 by area, from largest to smallest. Mongolia is immediately above it in that ordering, at 1,564,110 km². North Korea is immediately below it, at 120,538 km². This comparison uses the source’s area figures and subregions, not a ranking of all territories.
The marker shows the atlas location. Small countries may be too small for an outline at this scale. Map boundaries are illustrative.
People, languages and currency
The World Bank records 123,366,734 people for Japan in 2025. This is the latest non-empty annual observation in Roam’s committed 2020–2025 download, rather than a live population counter. Dividing that population by the source area gives approximately 326 people per square kilometre. This calculated average does not describe how evenly people are distributed.
The language entries in the source are Japanese. They describe the dataset’s listed languages, not every language spoken by residents. The currency listed for this date is Japanese Yen (JPY). Currency assignments are selected from Unicode CLDR’s date ranges for 23 October 2026; the three-letter codes identify currencies, not countries.
