I just found out that the population of Tokyo is 38 million people. Honestly, it sounds like an entire country rather than just a city. That's half of all France in one place! The population of Tokyo is so huge that it's hard to even imagine the scale. And if you take the whole of Japan, there are over 120 million. These are just crazy numbers for a single country. When you look at Tokyo's population and realize it's the biggest city in the world, it feels kind of strange. It's probably very densely populated there.
