When I first arrived in Tokyo, I had no idea how to eat sushi correctly, why people bow and how to greet or thank in Japanese.
I didn't know why people take their shoes off or that it's perfectly safe to carry large amounts of yen in my wallet, whilst getting lost in the darkest streets of Tokyo.
I know, I know, you can't believe one of the world's most densely populated cities can actually be silent.
It turns out, the merchant didn't even know how to use the card machine and offered me a staggering 15% discount for the inconvenience if I pay with cash instead.
