How long to set up a bank account in japan?

I�fll be moving to Japan soon, I�fll be landing there in a Tuesday afternoon.

I want to know how much time it takes on average to set up an bank account to take money transferences from my home country.

I need to know that to know how much cash I�fll need while i don�ft have an account to send money to japan. In an emergency I can use a debit card for sure, but in my country debit cards have way too many taxes and a bad exchange rate, so the best option is money transfer, and meanwhile I don�ft have an account to do so... the best option is taking enough money for the time period I�fll be without a bank account.

Thanks in Advance!

best advise is to keep your account in your home country in case.
Opening your account requires several things and requirements.
Are you having someone to support you?

Above is step by step guide on how to open Japan Post bank account.
You'll need an ID ( passport, zairyu card) , maybe a hanko/stamp(you might need to make it at shop), cash to deposit (1,000 yen is good enough). You'll need to fill the form in JAPANESE.
Best if you have someone to help you during that. Can be done within 30 minutes if everything goes smoothly.

That no one can tell you because you don't provide any information about what you'll be doing?
Are you going to be a student, working in Japan?
Cash for what? paying rent? eat ramen? maid cafe? buy manga?

Yes I will keep my account in my country! The only thing I�fm trying to avoid here is using my debit card, since that will make me waste money.

And the �gmoney I will need while I can�ft transfer�h is something I will calculate myself based on how long I�fll be there without a Japanese account, it was not meant to be a question.

Thanks a lot for the helpful info!!

I�fll be a student and I�fll need money to
Support myself while I can�ft transfer it to a Japanese account, so I�fll bring some cash. Plus I�fll pay first month�fs rent in cash as well.

you can open only ”ñ‹��ZŽÒ‰~—a‹à, an account for non-residents, when your resident term in Japan is less than 6 months. there are many restrictions to use it.
please confirm that the bank accepts money transfer from outside of Japan to your non-resident account. (they clearly say that you can't send money to outside of Japan during that term. but, it is unclear about receiving money. I am afraid you can't.)
I think your zairyu card must have an address (register your address at city office). you may need to have your "my number" (the number for tax purpose) to receive money from outside of Japan. also, you may be requested to show your student ID, which is issued by your school, when you are in student status. (when you open an account in JP bank.)

Apart from Japan Post an other foreigner friendly bank is Shinsei. I opened an account there (in one of their offices) and got my banking card immediately (if memory doesn�ft fail me). Later on I also opened an account at Citibank (now Prestia) because I was able to get a credit card through them.

As far as I know you need to be a resident in Japan (or at least I was). There might be other options as well, but as you write you�fll be a student I assume you�fll be a resident.

Regarding transferring money depending from
where you transfer it, you could use Transferwise which makes that both your outgoing transfer as well as the incoming one are local transfers only. It will take a few days and it requires you to register with your passport (as far as I remember)

Regarding paying your first rent. Please get information how much that is going to be. If you rent on the free market you often have to pay something like 5 months of rent before moving in: 2 months of rent, deposit, thank you money, agency fee... But for a student accommodation that might be different. Just ask if you already know where you will stay.

Enjoy your life in Japan.

I have a Shinsei account, and while the account opening and cash card issuing process was very fast, they threw a couple of obstacles in the way. For their accounts:
- You need a Japan mobile phone number or land line with a contract in your name. To get a phone number, you need to be resident. While I had a Japan 050 number, that was not sufficient, and the Yodobashi/BicCamera store I went to to get a voice sim was really difficult to deal with - took two hours to get it set up.
- For inward remittances you will need a "MyNumber" card. They take a while to issue. I have just had mine re-done, took a month.
- And while the cash card is issued on the spot, you can't use it until the pin number arrives in the post several days later. (And then JapanPost didn't put the delivery failure notice in my mailbox, so it took me three weeks to get it.)

And, yes, residency less than one year is going to make things harder.

Thanks for the replies again!

Yeah, of course I will have my debit card if everything goes wrong, but that will have me paying too many taxes and getting the worst exchange rates ever.

I will originally stay for only 6 months, maybe I�fll make it longer after I�fm in japan, but by now I�fll have a 6 months visa, so maybe that can be a problem huh.

As for the mobile phone, I think I�fll order a sim from Mobal, they are more expensive than the ones Japanese people actually use, but they are easier to get, order online and get it when I land in the airport, then activate it online. It gives you a actual 070, 080 Japanese number. It�fs meant for foreigners, but it�fs slightly more expensive.

Travelers checks.

Mobal have some mixed customer reactions - do some research on how good/bad they actually are first.
