Japan's complicated banking system and the restrictive security policies do not permit foreign creditcards to withdraw money from local ATMs.
Follow my "collection of hints", they do work (95% guaranteed - whatever that means in Japan
1. everybody already said it, creditcards
not issued in Japan do not work with local ATMs! (you even won't be able to enter the bank at night)
Not sure about American Express though.
2. and no, even banks like UJF, Mizuho etc. do not have international ATMs, although they have subsidiaries around the globe
3. almost all post offices even in the deepest countryside have an international ATM where you can withdraw money with "foreign" creditcards, also on weekends, so look for post offices and forget the banks
4. or find an international bank like Citybank (bigger cities only) with an international ATM - beware of international ATMs owned by private money exchangers, some charge a quite considerable fee!
5. you can go to
any bank, show your passport and creditcard and withdraw money when you do it
at the counter! Traveller Cheques work too (Thomas Cook etc.)
Banks are open on weekdays and close at 3 PM! So get enough money before the weekend.
Think well before trying to open a bank account.
Like in the silly adventures of Monkey Island, you need some grog and other things to complete the level.
- go to a local bank, get the required documents for opening a bank account and ask what they need from the City Hall
- get your personal hanko/inkan (in Japan you sign with your personal stamp, your signature is not valid, except for signing creditcard receipts, haha how ironic)
- register yourself at your local City Hall, take a Japanese friend with you (a "counter for foreigners" might imply that they speak English - yeah you wish...)
- a permanent address in order to get registered
- some Yen to pay for the stamped documents
- lots of patience
And say that you want to open a bank account and ask for the required documents (better double check).
After this and probably some more unconvenient visits to the City Hall, you'll get your Alien Registration Card (gaikokujin touroku shoumeisho), which is an official translation of your passport. Always show this together with your passport when asked for ID. Actually one might get the impression it's valued more than your passport...
Now that you completed this level, move on to the next stage. Go back to the bank, show your Alien Registration Card and the required documents - and always carry your hanko with you. You can enter the bank at 2:59 PM and they won't kick you out until you finished business. Okyakusama is okyakusama.
Side note: if you have a Japanese passport, skip all above steps
Opening the account should be pretty straightforward, they'll send your banking card to your permanent address within a few days!
There is one and only one bank in Tokyo where foreigners can open a bank account without all the hassle above, a valid passport is sufficient. But unfortunately I don't remember the name...
Oh I see, you're thinking about opening a post account? Although this is a bit easier and less restrictive, transferring money from your home bank to a Japanese post account might not work and you'll loose quite some money due to transfer fees
AND due to loss by exchange! Banks usually try to transfer money and even if the transfer gets rejected the money is considered to have moved and they handle it as if the transfer actually happened.
Best and most convenient thing you can do: use your creditcard!
- get cash at the counter or at any post office
- whenever possible, pay with creditcard and keep the cash because you need cash anywhere else
- and transfer money in advance to your creditcard, this way you can raise your limit by the amount of money you've payed in advance.
I don't know the fees for money withdrawal, but if you withdraw rarely and always as much as you can, the total cost might be equal to transferring money between your home bank and your Japanese bank account.
And for everyone not yet in Japan: although your bank at home might claim that they work together with banks in Japan and opening an account is no big deal and blabla - simply not true! And it's also the other way round, foreigners who come to Switzerland (where I live) can't just open a bank account. Our security policies are also very tight. But nobody tells you that until you get there, I bet...
P.S.: Opening a bank account at Citybank in your home country might do the trick, afaik you will be able to withdraw money from Citybank subsidiaries in Japan (but they're not really spread over the country)
Opening an account at Mizuho or any other Japanese bank in your home country will not work!
