Japan's population decline has reached a new milestone, with the country's Japanese-national population dropping below 120 million, according to a survey released Wednesday. The data also showed the biggest annual fall since comparable records began.

The latest figures highlight how quickly Japan depopulation is accelerating. By falling under the 120 million mark, the survey underscores the depth of the country's long-running demographic shift and the growing pressure created by a shrinking national population.

Because the survey refers specifically to Japanese nationals, the result does not describe every resident living in Japan. Even so, the report points to a clear nationwide trend that is drawing attention in Tokyo and beyond as policymakers track the impact of population loss.

The record annual decline is likely to intensify discussion around Japan's demographic future. With the Japanese national population continuing to contract, the new survey adds fresh urgency to concerns about how the country will manage the economic and social effects of depopulation.
