There is a good reason that I don’t keep my savings in a Japanese bank — the interest they pay. While you may think that the percent interest that your bank pays is low, it’s nothing compared to Japanese banks.
As you can see, the Japanese post office pays a whopping 0.02% (note that isn’t 0.2% – it’s 200ths of a percent) for a year commitment of your money. That means if you deposit $10,000 into the postal savings system, at the end of the year you’ll have $10,002 to your name. Nor of course, if you are willing to lock your money up for a longer time, you can get a better interest rate. Agree to have you money locked up for 4 or more years and you’ll make $7 a year for every $10,000 you deposit.
Makes you want to put all your savings into a Japanese banks, doesn’t it?
