## Prompt

As of the most recent available estimate, what is the population of Japan, and is it increasing or decreasing? Give the figure and year, and cite sources.

## Response

Japan’s **most recent available estimate** in the results is **122,427,731 people in 2026**, and it is **decreasing** rather than increasing.[1] Worldometer’s 2026 table shows a **yearly change of -675,748** and a **yearly % change of -0.55%**, which confirms the decline.[1]

Japan’s official Statistics Bureau estimate also shows a decline: **124,352 thousand** as of **October 1, 2023**, down **595 thousand** from the previous year, a **0.48% decrease**, and it notes that the total population had fallen for the **thirteenth year in a row**.[4]

Would you like the latest **official** estimate only, or a brief comparison of the different population estimates in your results?
