Japan’s population story blends modest annual growth with a rapidly changing age structure. In 2023, people 65+ accounted for 29.0% of residents, while younger cohorts make up smaller shares and overall dependency pressures rise. Patterns also vary by place, with 91.8% of people living in urban areas and Tokyo drawing a large share. We connect these demographic shifts to health, housing, workforce, and mortality trends.
