Western Union in Japan - exchanging money

Hi all,

We are going to Japan for a trip soon and I wanted to check if anyone has experience of sending money to yourself to withdrawl in a Western Union japanese branch.

The objective is to automatically exchange money, for example:
- Sending 1000 USD -> receiving equivalent in JPY
- Sending 1000 EUR -> receiving equivalent in JPY
- Sending 1000 BRL -> receiving equivalent in JPY

Of course for many of you there might be better options, but for Brazilians, doing this through Western Union would save quite a bit of taxes making the exchange much better.
If I went that way, what document would I need to withdrawl my money in Japan? Only a passport? Any additional document?

Thanks for the support!

in general, when you receive money sent from a foreign country (also sending money from Japan), you have to show your "my number", ID for tax purpose, mainly. but, you don't have it, because you are not a resident. it is a law for preventing money laundering. probably, you can't get your money in Japan. you should ask western union branch in Japan in details.
