Japan’s national census, a quinquennial review of its demographics, has revealed a significant and concerning decline in population. The latest figures indicate a drop of over 3 million people since the 2020 census, bringing the total resident population to just over 123 million in 2025. This marks a 2.45% decrease over five years and pushes Japan’s population count back to levels not seen since approximately 1989.

The report, released by the Statistics Bureau of Japan (SBJ), paints a stark picture of a nation grappling with a deepening demographic crisis. This contraction is the third consecutive decline recorded in the census, exacerbating a trend that has seen a 0.7% decrease between 2015 and 2020. Since the inception of census-taking in 1920, such a pronounced demographic downturn has never been documented.

Widespread Decline Across Prefectures

The population loss is not confined to specific regions but is a widespread phenomenon affecting the vast majority of the country. Out of Japan’s 47 prefectures, 45 experienced a population decrease in the last five years. Some prefectures saw particularly sharp declines, with Hokkaido losing 239,000 residents, Shizuoka losing 164,000, and Hyogo losing 141,000 compared to 2020 figures. Notably, some areas that had previously seen population growth have now joined the list of declining prefectures.

The exceptions to this trend are the metropolitan area of Tokyo and Okinawa. Tokyo saw an increase of 199,000 residents, bringing its total to approximately 37 million, accounting for 30% of the nation’s population. Okinawa recorded a modest gain of 1,000 inhabitants. The population density in Tokyo is considerably higher than the national average, with around 6,400 people per square kilometer compared to just over 300 nationwide.

Future Projections and Economic Impact

These latest census figures align with the more pessimistic projections made by the National Institute of Population and Social Security Research (IPSS). The IPSS has forecasted that Japan’s resident population could fall to 87 million by 2070, with individuals aged 65 and over constituting nearly 40% of the census.

The implications of this demographic shift extend beyond mere numbers, posing significant challenges to Japan’s economy, healthcare system, defense capabilities, and overall social welfare. Experts suggest that the declining population is already impacting the economy, contributing to issues such as millions of vacant homes, schools being repurposed due to lack of students, and the closure of healthcare facilities.

A Persistent Challenge: Low Birthrate

Despite considerable government efforts to reverse the trend, the core issue remains Japan’s alarmingly low birthrate. Recent official data indicates that the number of births has fallen to levels not anticipated until 2042. While immigration has been suggested as a potential solution, it faces political headwinds, with a rise in nationalist sentiments advocating against increased foreign residency. Currently, foreign residents constitute less than 3% of Japan’s total population.

James Raymo, a demographer at Princeton University, commented to The New York Times that Japan has reached a point where this demographic decline is irreversible in the short to medium term, and significant immigration is unlikely. He also pointed out that Japan’s situation is not unique, serving as an early indicator for many other nations in Asia and beyond that will face similar demographic challenges.
