ATMs

Thus far (3 weeks in Korea and 3 weeks in Japan) finding ATMs that will accept my chase debit card has been extremely difficult. To date, have found only 2 ATMs in Japan that took my card; many don't accept foreign cards and those that do typically won't accept mine. I often get a message saying my card is invalid or expired. 

Western hotels in large cities accept my chase credit card and they will exchange currency but both countries are still largely cash economies. Post offices seem to be the best bet where one can find an ATM that accepts foreign cards.
