Japan Demographics 2026: Births Fall to a Record Low as Fertility Reaches 1.14

Japan recorded 671,236 births in 2025, the lowest annual total in the official series, while the provisional total fertility rate fell to 1.14.

Primary official values use Statistics Bureau of Japan population estimates and census releases. Fertility, births, deaths and natural change use MHLW/e-Stat, including the 2025 provisional annual results published on June 3, 2026. Long-run mid-year series, projections, median age, density, urban estimates, world share and global rank use UN DESA World Population Prospects 2024 medium variant as presented in the Worldometer tabulation.

Demographic Overview

Population direction

Official annual estimates and UN mid-year estimates both show a declining population path. The official 2024 estimate records a decline of 550,000 people.

Age structure

The 65+ population reached 36.243 million in 2024, while the 0-14 group was 13.830 million.

Fertility pattern

The provisional 2025 total fertility rate was 1.14 births per woman, the lowest value in the official series.

Natural change

Deaths exceeded births by 918,253 in the 2025 provisional results. The natural balance remained negative for the nineteenth consecutive year.

Urban profile

The UN WPP tabulation estimates the 2026 urban population share at 93.35%, with 114.292 million people in urban areas.

Projection path

The UN WPP 2024 medium variant projects Japan below 120 million by 2030 and near 105 million by 2050.

Method note
  • Official resident estimates are used for Japan’s annual population estimate and broad age structure.
  • UN WPP values are used where a long, comparable mid-year series or projection path is needed.
  • MHLW data is used for births, deaths, fertility and life expectancy because these indicators come from national vital-statistics and life-table systems.
  • Projection rows are kept separate from historical and current rows.

Methodological Safety Note

Methodological Safety Note: Japan demographic values can differ by source because resident estimates, preliminary census counts, mid-year model estimates and projections measure different things. Official Statistics Bureau values are preferred for current resident population and age structure. UN WPP values are used for long-run international comparability and projections. MHLW values are used for births, deaths, fertility and life expectancy. The 2025 vital-statistics values are provisional, while the displayed 2024 comparison values are final. Rounded values may not sum exactly. Net migration is not the same as immigration admissions. Urban population depends on the source definition. Sex ratio here is calculated from official male and female totals, while a full population pyramid requires detailed age-by-sex rows.

Japan Demographics FAQ

What is Japan’s population?

The Statistics Bureau preliminary population indicator shows 122.81 million as of May 1, 2026. The preliminary 2025 census count was 123,049,524 as of October 1, 2025.

Is Japan’s population growing?

No. The official October 2024 estimate shows a decline of 550,000 people, or -0.44%, over the year.

How old is Japan’s population?

The official 2024 estimate places 29.3% of the population at age 65 or older. The UN WPP 2026 medium-variant tabulation gives a median age of 50.2 years.

How many births did Japan record in 2025?

MHLW’s provisional annual results record 671,236 births in 2025, the lowest annual total in the official series and the tenth consecutive yearly decline.

What is Japan’s fertility rate?

MHLW Vital Statistics report a provisional total fertility rate of 1.14 births per woman in 2025. Final rates are scheduled for December 2026.

Why is there no full population pyramid?

A full population pyramid requires validated five-year age groups by sex. The current page dataset includes official broad age groups and total male/female counts, so it does not label those broad groups as a population pyramid.
