All ages and both sexes at mid-year. The value is estimated or projected, not a headcount taken on one day.
Urban share
The percentage living in areas classified as urban by national criteria; definitions differ between countries.
Density
122,427,731 people divided by 364,555 km² of land area.

Primary evidence
One named source, visible limits
Figures use the Medium variant of the 2024 Revision. The UN series covers 237 countries or areas; estimates and projections from 1950 to 2100 and is built from 1,910 population censuses and 3,189 nationally representative sample surveys, alongside vital-registration and other demographic systems.
These are demographic estimates and projections for Japan population and demographic indicators, not a live register of identifiable people. Mid-year values refer to 1 July; moving counters interpolate a published annual flow between anchors.
