Jakarta overtakes Tokyo as world’s most populous city, according to UN

Thursday, November 27, 2025 -Jakarta has officially surpassed Tokyo to become the world’s most populous city, the United Nations reports. 

The rapid growth highlights significant urbanization trends, with Jakarta now facing mounting challenges related to infrastructure, housing, and public services as it adapts to its expanding population.

Experts warn that the city’s surge in residents puts pressure on transportation networks, healthcare, and environmental management, particularly as Jakarta grapples with flooding and land subsidence. 

Urban planners are calling for urgent investment in sustainable development, smart city initiatives, and disaster preparedness to accommodate the city’s growing demands.

The demographic milestone underscores broader global shifts toward megacities, with implications for economic activity, resource allocation, and governance. 

Analysts suggest that Jakarta’s rise will influence regional planning, investment strategies, and international attention on Southeast Asia’s urban growth challenges.
