Claim
Tokyo, the world's third-largest city by metropolitan population
Correction

This caption mixes up city-population and metropolitan-population rankings. Authoritative sources describe Greater Tokyo as the world's largest metropolitan area, not the third-largest.

Full reasoning

This caption is incorrect because Tokyo is widely identified as the world's largest metropolitan area, not the third-largest.

Two official Tokyo Metropolitan Government pages say this directly:

  • Invest Tokyo says: "The Greater Tokyo Area has a population greatly surpassing that of major world cities ... standing at approximately 37.8 million people" and labels Tokyo as having the "Highest Population among the World Metropolises."
  • Another Tokyo Metropolitan Government page states: "With 37 million residents, Greater Tokyo is the most populous metropolitan area in the world."

An OECD report also says: "Tokyo is the largest metropolitan area in the world".

The likely source of confusion is that the UN's 2025 city/urban-agglomeration ranking places Tokyo third by city population behind Jakarta and Dhaka, but that is not the same thing as metropolitan population. So the caption's use of "third-largest ... by metropolitan population" is wrong.
