Can I use my credit cards? If yes, what is the best way to carry money in Japan: Travelers Checks, cash or credit cards?
Although most stores and restaurants will accept VISA, MasterCard and American Express cards, travelers should keep in mind that there are smaller shops that may not have merchant account capabilities. More than 26,000 Post Office ATMs exist at various locations throughout Japan, and stickers indicate whether a Post Office has an ATM machine. Cirrus, Plus, Maestro and Visa Electron networks are accepted, as are Visa, MasterCard, American Express and Diners Club credit cards. Japan has one of the lowest crime rates in the world, so carrying cash is not a real problem. Travelers Checks are also an option, although it is wise to have these available in either Japanese yen, or US dollars. Travelers Checks may not be accepted by establishments other than major hotels and banks, as establishments must have currency exchange capabilities in order to accept these.
