The /us part is not needed, because it's default (https://itunes.apple.com/album/id12345 is by default the us page), so through "itunes_lang = jp" one can manually put the /jp, but I had to put an extra parameter for that. And I had to name it "itunes_lang" because other website may need language shifts too. If they don't I could change it to "lang = jp" or even only jp. That;s why I asked with amazon.
