Japan’s population drops to 123.05 million as census decline hits record high
The 2025 national census figures, released by the government and reported by NHK News Japan, show a loss of nearly 3.1 million people since 2020, underscoring the scale of the demographic challenge facing the administration.
Japan’s population has fallen to 123.05 million, according to preliminary results from the 2025 national census released by the Ministry of Internal Affairs and Communications. The data, which NHK News Japan reports as the latest available figures, indicates a decrease of 3,097,000 people compared to the 2020 census baseline.
This latest survey marks the third consecutive five-year period in which Japan’s population has contracted. The Ministry’s announcement confirms that the rate of reduction in this interval has reached a record high for these periodic national counts, signalling an acceleration in the country’s demographic decline.
The figures are currently classified as preliminary or "fast" values. While they provide an immediate snapshot of the national headcount, the government has noted that final, detailed demographic breakdowns may differ slightly upon the publication of the full census report.
The acceleration in population loss presents significant implications for public policy and governance. A shrinking workforce and changing age demographics typically necessitate adjustments in social security frameworks, labour market regulations, and regional planning strategies.
The Ministry of Internal Affairs and Communications continues to monitor these trends as part of its statutory duty to collect and disseminate national statistics. The preliminary data serves as an early indicator of the structural shifts that will likely dominate policy discussions in the coming legislative sessions.
