Population density (people per sq. km of land area) in Japan was reported at 342 sq. Km in 2023, according to the World Bank collection of development indicators, compiled from officially recognized sources. Japan - Population density (people per sq. km) - actual values, historical data, forecasts and projections were sourced from the World Bank on October of 2025.

Historical dataset showing Japan population density by year from 1961 to 2022.

Japan JP: Population Density: People per Square Km data was reported at 347.778 Person/sq km in 2017. This records a decrease from the previous number of 348.350 Person/sq km for 2016. Japan JP: Population Density: People per Square Km data is updated yearly, averaging 337.674 Person/sq km from Dec 1961 (Median) to 2017, with 57 observations. The data reached an all-time high of 351.339 Person/sq km in 2008 and a record low of 258.912 Person/sq km in 1961. Japan JP: Population Density: People per Square Km data remains active status in CEIC and is reported by World Bank. The data is categorized under Global Database’s Japan – Table JP.World Bank.WDI: Population and Urbanization Statistics. Population density is midyear population divided by land area in square kilometers. Population is based on the de facto definition of population, which counts all residents regardless of legal status or citizenship--except for refugees not permanently settled in the country of asylum, who are generally considered part of the population of their country of origin. Land area is a country's total area, excluding area under inland water bodies, national claims to continental shelf, and exclusive economic zones. In most cases the definition of inland water bodies includes major rivers and lakes.; ; Food and Agriculture Organization and World Bank population estimates.; Weighted average;

In 2020, the population of Tokyo Metropolis amounted to over ***** inhabitants per square kilometer. The number increased from approximately ***** inhabitants per square kilometer in 2000.

WorldPop produces different types of gridded population count datasets, depending on the methods used and end application. Please make sure you have read our Mapping Populations overview page before choosing and downloading a dataset.

-Unconstrained individual countries 2000-2020: Population density datasets for all countries of the World for each year 2000-2020 – derived from the corresponding Unconstrained individual countries 2000-2020 population count datasets by dividing the number of people in each pixel by the pixel surface area. These are produced using the unconstrained top-down modelling method.
-Unconstrained individual countries 2000-2020 UN adjusted: Population density datasets for all countries of the World for each year 2000-2020 – derived from the corresponding Unconstrained individual countries 2000-2020 population UN adjusted count datasets by dividing the number of people in each pixel, adjusted to match the country total from the official United Nations population estimates (UN 2019), by the pixel surface area.

Over the last decade, Japan’s population has aged more and more, to the point where more than a quarter of Japanese were 65 years and older in 2022. Population growth has stopped and even reversed, since it’s been in the red for several years now.

It’s getting old

With almost 30 percent of its population being elderly inhabitants, Japan is considered the “oldest” country in the world today. Japan boasts a high life expectancy, in fact, the Japanese tend to live longer than the average human worldwide. The increase of the aging population is accompanied by a decrease of the total population caused by a sinking birth rate. Japan’s fertility rate has been below the replacement rate for many decades now, mostly due to economic uncertainty and thus a decreasing number of marriages.

Are the Japanese invincible?

There is no real mystery surrounding the ripe old age of so many Japanese. Their high average age is very likely due to high healthcare standards, nutrition, and an overall high standard of living – all of which could be adopted by other industrial nations as well. But with high age comes less capacity, and Japan’s future enemy might not be an early death, but rather a struggling social network.

Population density of Japan slipped by 0.44% from 344.8 people per sq. km in 2021 to 343.3 people per sq. km in 2022. Since the 0.16% downward trend in 2012, population density declined by 1.96% in 2022. Population density is midyear population divided by land area in square kilometers.

This dataset displays data from the 2005 Census of Japan. It displays population, population change, area, and population density of the 47 prefectures in Japan. This data comes from Japan's Ministry of Internal Affairs and Communication's Statistics Bureau

Adults with 100 thousand to *********** U.S. dollars in wealth made up around ** percent of the Japanese population in 2020, while the second largest share of people were worth between 10,000 and 100,000 dollars. Together, these groups accounted for approximately ** percent of the population.

Wealth versus income

Wealth, as opposed to income, measures the ownership of assets in a society. Together with GDP, GDP per capita, and household disposable income, it helps to understand the economic well-being of households. Furthermore, the distribution of wealth gives an indication about the degree of equality in a society. Illustrated by its wealth distribution, Japan can be considered relatively equal compared to other countries.

Egalitarian corporate culture

In recent years, wealth inequality has become the subject of increasing focus among policymakers, academics and the general public. While several factors have contributed to the high equality in the country, it is safe to say that the egalitarian ethic in Japanese corporate culture is one of these reasons. This is reflected, for example, in the income structure; Japanese CEOs earn remarkably less than their counterparts in the United Kingdom or the United States. In a ranking of the average income of business leaders worldwide by country, Japan did not even make it into the list of the top ten countries.
