China and India may be the nations with the highest population, but Japan is home to the most populated city. In 2022, the population of the Tokyo metropolitan area is estimated to be an astounding 37.7 million people, with 13.96 million living in the city itself. To compare, greater Tokyo’s population is almost equivalent to the total sum of the 25 most populated cities in the U.S., which adds up to 37.8 million people. It’s also 1.5 times larger than the next most populous metro area, Seoul.
