Tokyo

1. Contrary to the persistent myth, Japan is cheap! My hostel in Tokyo is cheaper than the hostel I work at in Sydney. Coffee flavoured milk is 1/3 the price I pay in Sydney!
   
2. It can be very very difficult to find an ATM that accepts foreign cards or is open late at night.
3. The order of books on the shelves of a bookshop is entirely inscrutable even if you know your kana and a few kanji.
