Tokyo is both the capital and most populous city of Japan, with over 13 million inhabitants.
What makes the ‘perfect capital city card’ ? In my opinion a proper view of the city with name of the city on the foreground. So this card matches my criteria pretty much. But.. on closer inspection the card shows 'only' Nishi-Shinjuku, a skyscraper business district in Tokyo. Not sure if this is the 'best representation' of the city.
