Asia · Eastern Asia
Japan is recorded at 123.75m people in 2024, with total annual change of -636,276 under the WPP medium variant.
Japan observed 2023 population pyramid, grouped into five broad age bands from WPP single-age male and female arrays.
Population identity: births minus deaths plus net migration equals total change within the Record tolerance.
