No. 1: Tokyo, Japan
I’m sure you all know Tokyo, Japan’s capital. But did you know that Tokyo-Yokohama is the largest metropolitan region in the world? ‘Only’ 10 million people live in the city of Tokio itself, but when you put Tokyo, Yokohama, Kawasaki and Saitama together, a region which encompasses an area of just 14,000km², you’re looking at a population of almost 38 million! In comparison: Lusatia, a region that straddles the border between Germany and Poland, is almost the same size with an area of 13,000km², but it’s home to only 1.3 million people. As you’d expect, living space is so cramped in Tokyo-Yokohama that people have to live in tiny apartments or live together with their families their whole life in the smallest spaces. Rent is astronomical. The high density of inhabitants is reflected in the traffic – it’s not uncommon to see eight-lane traffic jams piling up for hours at a time. In order to buy a car you need to be able to prove that you own a parking space, which can cost up to nearly £300 a month. Space is definitely one thing that’s lacking here!
