Sorry, this feature is not available anywhere in Japan. In fact, it is not possible to pay for your purchase by either credit or debit card. Japan is still a cash society. The only choice for foreigners who run out of money is to go to the local postoffice, or a branch of CitiBank. where they can use their debit or credit cards to get local currency. Remember that each time you make a purchase and add cash back in the US, you are charged a withdrawal fee. To reduce the number of withdrawal fees, you should exchange about enough money so you will have 50,000 yen when you arrive in Japan. Then, if you run out, you will only need to make 2 or 3 additional withdrawals depending on the length of your stay and spending habits.
