How can I exchange Japanese yen in the united states? (California)?

Question:

And can I use my wells Fargo or bank of America debit card to withdrawal yen in Japan? Like if I have dollars in my account and I withdrawal in Japan will it exchange it out on it's own and give me yen?

Thanks! It's been really hard finding exact information on this.

Answer:

Yes, if you go to a major bank or to the local post office, you can use your debit card.
