Should i exchange foreign currency at home or at destination? Should I use ATM...

...or Foreign Exchange Service? I am heading to Japan from Australia and am wondering what the most economical way is for me to exchange my currency. Should i do it in Australia or wait till i get to Japan? Should i use ATM's or should i use a foreign exchange service? Your help would be great!

best way is wait to be in Japan, directly in to the airport you'll find exchange desk with no fee or a cheap one for cash,
ATM is always available for visa, american express and so on,
some time it's cheaper and faster to change some cash money.
