As it’s not the same changing trains in your hometown as it is in a megalopolis like Tokyo, we’d like to set you a challenge: head to a metro station wearing these oversized earrings and try to take on the city’s thirteen lines, two hundred and seventy stations, never-ending passageways and millions of passengers who, just like you, are scurrying around like ants from one place to another. And if you don’t fit on the train you’ve chosen, you have two options: either let yourself be pushed on by a lovely gentleman and join the other sardines, or try your luck at another stop!
