Someone wrote in to ask about sending postal money order from Japan to country A,B,C or Z. Well, there are several steps of doing it and one of the simplest and cheapest way to do it is via International Postal Money Order.
First, you need to purchase International Money Orders (kokusai kawase) from your closest post office. You will need to fill out a remittance form and also the front of the money order form.
Then, you will tell the teller the amount you want to send in Yen, which will then be calculated according to the daily exchange rate of the currency of the country you are sending money to. For example, if you are sending money to Canada today, the teller is going convert Yen to CDN according to the exchange rate today.
A few tips though, you must understand that one international postal money order cannot exceed $700, so if you want to send, say $1000, you will need get two Kokusai Kawase forms from the teller. The fee for sending ¥200,000 is ¥1,000, currently. It is of course subject to change.
This method of sending money is cheapest but you may need to wait 6-14 days for it to be processed and received.
