1. Tokyo: The Capital of Japan

Tokyo is situated on the largest island of Japan, which is Honshu.

Many people don’t know that it was once a small fishing village named Edo.

Over the Meiji Restoration in 1868, the name was changed to Tokyo. And from this time, the city started to grow rapidly economically.

That’s why by 1900, its population passed 2 million, and in 1940 it became home to more than 7 million people.

Tokyo city

The only time it saw major residents decline was at the time of World War II.

When Japan surrendered in 1945, its total number of inhabitants was just 3.5 million.

The major reason behind this was the airstrike that took nearly 100,000 people’s lives in Tokyo on March 9, 1945.

And around a million were estimated to be left homeless and temporarily left the city.

However, after the end of the war, the city started to gain its residents again.

Now it’s the most populated city in Japan and one of the best living areas for foreigners.


Tokyo is Japan’s leading industrial center with a highly diverse manufacturing base.

Although the city was rebuilt quickly, unfortunately, it saw colossal damage again by the Allied air raids during World War II.
