Apple used to have strong statements about the seriousness of using services while outside the region.
"Our Services are available for your use in your country of residence (“Home Country”)."... " Any other use of the Services and Content is a material breach of this Agreement. Apple may monitor your use of the Services and Content to ensure that you are following these Usage Rules."
Even older wording was more specific: "The iTunes Service is available to you only in the United States, its territories, and possessions. You agree not to use or attempt to use the iTunes Service from outside these locations. Apple may use technologies to verify your compliance."
In other words it could have been interpreted as meaning if you lived in the USA and went on vacation to Japan and tried to download music you had purchased while in the USA and they caught you by tracking from where you were downloading, they would consider than an outright violation of a contract to which you had agreed and take whatever measures they deemed it merited.
Apple has greatly backed off, on paper at least, that position and only states, "Our Services are available for your use in your country or territory of residence (“Home Country”). By creating an account for use of the Services in a particular country or territory you are specifying it as your Home Country", and, "Certain Services and Content available to you in your Home Country may not be available to you when traveling outside of your Home Country." They are still saying if you create an account in a country you are declaring you live in that country and their services are offered for use in that country. If you travel outside of that country and find the services don't work then you don't have any right to insist they should.
I guess it also depends upon what they consider to be a breach of the agreement: "If you fail, or Apple suspects that you have failed, to comply with any of the provisions of this Agreement, Apple may, without notice to you: (i) terminate this Agreement and/or your Apple ID, and you will remain liable for all amounts due under your Apple ID up to and including the date of termination; and/or (ii) terminate your license to the software; and/or (iii) preclude your access to the Services." Does claiming you live in Japan when you really don't constitute a serious breach?
