I live in Japan and am trying to bring a large amount of dollars from the US. While in the States last week, I found that my mother's bank offered TC for free, so I bought $9000 worth and brought them back. After exiting customs (KIX) I went to the foreign exchange booth to change into yen. They were nearly 2 yen per dollar more valuable than cash. However, they would only change $3000 per day. Frustrating. Now I have to go to a bank.
