How do I get local currency?

You can get Japanese currency at some banks in the U.S. before you leave, but (1) it takes a bit of time: usually you have to order it; and (2) don’t get very much. You may want about $300 in Japanese yen at most before you enter Japan. You can also get some when you arrive in Tokyo, at the Narita airport exchange counters.

Usually you get better rates in Japan itself, and banks (or your own debit cards) give the best rate. Check your bank’s fee for using ATMs in Japan. Using credit cards for purchases also gives a good rate. ATMs in post offices and 7-Eleven convenience stores accept cards issued outside of Japan, and there is a 7-Eleven near the KCP campus.  Having some cash on hand for emergencies is useful.
