In 2023, the population in urban agglomerations of more than 1 million in Japan stood at 81.3 million. From 2024 to 2028, a forecasted declining trend reflects a gradual reduction in urban agglomerations’ population, dropping from 81.2 million to 80.806 million. Year-on-year, this represents minor decreases of 0.13% to 0.11%, with the Compound Annual Growth Rate (CAGR) over the 5-year period being approximately -0.12%.
Future trends to watch for include the effects of Japan's aging population on urban demographics and potential growth in suburban areas as digital and remote working impacts living choices. Additionally, government policies encouraging urban rejuvenation or migration might alter this decline.
