Introduction
Population projections estimate the expected number of people living in a given area at future points in time, serving as a critical planning tool for understanding long-term demographic development, resource allocation, and social welfare needs.
Future population dynamics in Japan depend on projected birth rates, death rates, migration patterns, economic conditions, and social policies.
Data come from FAO's Population and Employment statistics, which compile harmonised population data and projections from national statistical offices and international organizations. These projections extend through 2100 and provide comprehensive coverage of expected population trends by gender, urban/rural residence, and other demographic characteristics.
Total Population Projection
Japan's total population is projected to reach approximately 76,846,000 people by 2100, marking a significant population decline driven by fertility rates well below replacement level, with profound implications for future population size, age structure, and economic sustainability.
Population Projections by Gender
Gender composition patterns reveal how demographic trends will shape future population balance and social structures.
Male Population Projection
Japan's male population is projected to reach approximately 36,979,200 people by 2100, experiencing significant decline as fertility rates continue their downward trajectory, reflecting broader demographic contraction.
Female Population Projection
Japan's female population is projected to reach approximately 39,866,700 people by 2100, experiencing significant decline as fertility rates fall below replacement level and demographic momentum shifts decisively toward population contraction.
Population Projections by Residence
Urban and rural distribution patterns illustrate how economic development and demographic shifts will reshape where people live in the coming decades.
Urban Population Projection
Japan's urban population is projected to reach approximately 103,039,000 people by 2100, declining alongside overall population trends, though maintaining a larger share relative to rural areas as urbanization continues.
Rural Population Projection
Japan's rural population is projected to reach approximately 5,755,540 people by 2100, experiencing substantial contraction as economic opportunities and infrastructure improvements drive sustained movement from rural to urban areas, compounded by overall population decline.
Frequently Asked Questions
Japan's population projections are primarily driven by the expected balance between birth rates and death rates. Like many developed European countries, Japan faces low fertility rates that remain below replacement level, which means the population would naturally decline without immigration. The projected population by 2100 of approximately 76,846,000 people reflects a transition from growth to decline, as demographic transitions advance and fertility rates continue to decrease, while immigration plays a crucial role in moderating population decline.
Urbanization is projected to significantly shape Japan's population distribution, with the urban population projected to reach approximately 103,039,000 people by 2100. This projected trend reflects ongoing economic development, as cities offer better employment opportunities, access to services, and improved infrastructure. However, rapid urbanization also presents future challenges including housing shortages, infrastructure strain, and environmental pressures. Meanwhile, rural populations are projected to continue representing a substantial portion of Japan's population, particularly in regions where agriculture remains important.
Japan's projected population maintains a relatively balanced gender composition, with the male population projected at approximately 36,979,200 people and the female population at approximately 39,866,700 people by 2100. Gender balance varies by age group, with differences reflecting expected gender-specific mortality patterns, life expectancy variations, and birth sex ratios. Women are projected to continue having longer life expectancy, which affects gender composition particularly in older age groups.

Methodology and Data Sources
All charts and indicators are based on FAO's Population and Employment statistics, which include historical data and projections through 2100, compiled from national statistical offices and international organizations worldwide. These projections are updated periodically and provide comprehensive coverage of projected total population, gender distribution, and urban/rural population breakdowns across all countries. Population projections are subject to assumptions about future fertility, mortality, and migration trends and may differ from actual future population outcomes.
