I have a small trip to Germany coming up in a few days and was looking around for the best way to convert my yen to euros. It seems that using ATMs in Germany would provide the best rate, but I would like to have some local cash on hand before heading for my hotel.

Could anyone tell me what the commission rates are at Frankfurt Airport for currency exchanges, so that I can decide whether it will be better to do the exchange here in Japan, or when I arrive in Germany?
