Tokyo is often considered one of the most densely populated cities in the world, particularly when looking at the Greater Tokyo Area, which is the largest metropolitan area globally by population. The population density in Tokyo varies widely depending on the district. Some central areas have extremely high population densities, while others are less dense.
The Greater Tokyo Area includes Tokyo Metropolis and parts of surrounding prefectures like Kanagawa, Saitama, and Chiba. It has a population of over 37 million people. Within the 23 special wards of Tokyo, the population density can exceed 6,000 people per square kilometer, with some districts, like Shinjuku and Shibuya, reaching even higher densities due to the concentration of businesses, residences, and amenities.
Despite its high density, Tokyo is known for its efficient urban planning, extensive public transportation system, and innovative use of space to accommodate its large population.
