I assumed that while I was in Japan, I would be unable to use the US iTunes store. However, I was able to use it during my entire stay in Japan and purchase music and video normally. I guess that because the account was set up in the US, it allowed me to operate as though I was in the US. Interestingly enough, I had no trouble accessing any US websites EXCEPT Disney.com which automatically switched over to the Japanese sight. I'm sure that doesn't help most of you living abroad wanting to access the US iTunes store, but for those of you with laptops who travel to the US...that might be a way around?
