What We Found

The claim that Japan's population reached 124 million in 2026 is inaccurate. Multiple authoritative sources, including the Japanese Ministry of Internal Affairs and Communications and United Nations projections, estimate Japan's total population to be approximately 122.4 million in 2026.

Evidence

The claim that Japan's population reached 124 million in 2026 is contradicted by official government data and international demographic projections. According to the Japanese Ministry of Internal Affairs and Communications, the total population of Japan (including foreign residents) was approximately 123.77 million as of January 1, 2026. Other reputable sources, such as the United Nations World Population Prospects 2024 and StatisticsTimes, project the total population for 2026 to be approximately 122.43 million. Furthermore, the number of Japanese nationals residing in Japan has fallen below 120 million, standing at approximately 119.74 million as of early 2026. The discrepancy between the claim and the data suggests an overestimation of the country's current population size.

What's Missing or Misleading

The claim fails to distinguish between the total population (which includes foreign residents) and the population of Japanese nationals, both of which are below the 124 million figure cited. It also ignores the well-documented trend of population decline in Japan.
