The entire area of ​​mainland japan is roughly the same size as the US. What state does it mean?

When comparing Japan's total land area to that of the US, it's often said to be similar in size to the state of California! To put it into perspective, California covers about 163,696 square miles, while Japan is approximately 145,937 square miles in size. So, the Golden State is a great mental image when you're picturing the landmass of Japan! Although Japan has a smaller land area, its population density is one of the highest in the world. This lush island nation supports around 126 million people, making urban areas like Tokyo packed with life. In contrast, California, with its sprawling terrains ranging from beaches to mountains, has a population that's roughly 40 million, meaning Japan is an exciting tapestry of culture and innovation layered much more densely!
