I've gotten varying input as to which of the above is best to use. I've been told not all ATM's will take American debit cards. I've also been told cashing traveler's checks is a long process.
Others have told me credit cards are not widely accepted outside of Tokyo and Kyoto and it's necessary to pay for most everything, including hotels, in cash.
Would love some input on the best way to get money for a 3 1/2 week trip.
