Tokyo is often considered the largest city on Earth because when we include the surrounding cities like Chiba, Kawasaki, Sagamihara, Saitama, and Yokohama, it forms a massive urban area. However, it’s important to note that Yokohama is actually Japan’s second most populous city.
Over time, these cities have grown and expanded, and their outskirts have gradually merged together. This has created a gigantic region where it’s difficult to tell where one city ends and another begins. This interconnected urban area is often called a conurbation or megalopolis.
It’s astonishing to know that around 28% of Japan’s entire population lives in this vast urban region. That’s a significant portion of the country’s people residing in this area with its extensive network of buildings and streets. It’s like a huge, sprawling city that stretches as far as the eye can see.
