Money in Tokyo
The official currency in Japan is the Yen (¥, JPY) and, despite what you might think, credit cards are barely used.
In Japan, you can find coins of 1, 5, 10, 50, 100 y 500 yen, and bills of 1,000, 2,000, 5,000 and 10,000
Credit Cards
Credit cards are accepted in hotels and in the larger shops in the bigger, more important cities. But despite having a reputation for advanced technology, Japan is one developed nation where credit card payment hasn't really taken off. The Japanese usually use cards such as the Suica and Pasmo.
If you're thinking of visiting the more remote cities of Japan, better to bring cash.
Where can I change money?
To pay as little commission as possible we recommend that you bring euros or dollars and change them to yen in the banks or exchange points in Japan.
Banks and ATMs
The other option, and perhaps the most convenient one, is to directly take yen out of the ATMs. You'll find 24 hour ATMs in some banks and in 24-hour shops such as 7-Eleven.
Before travelling you can ask your bank what commission they will take for withdrawing money in other currencies, but the standard fee is 4%.
Changing Money Beforehand
If you don't want complications on your trip, the best thing to do would be to change money before leaving. You can do this at a bank, although commissions tend to be quite high.
Tipping
In Tokyo, it's not common to tip, and if you leave money on the table in a restaurant, they're likely to think you've forgotten it and will chase you to give it back!
Exchange Rate
A euro is worth 130JPY, a dollar 109 and a pound 143.
