This is odd. Apple Japan's website uses the pre-iPhone design - tabbed style. I wonder if this is related to the lack of iPhone's abroad or perhaps the lack of resources being put into Apple Japan.
Is Apple ignoring its foreign markets, because they are all iPhone or nothing right now?
After all, Apple's Japan sales are still anemic and will stay there until Apple releases a product of real interest to Japanese - such as an ultraportable laptop.
I'll have to check other foreign Apple sites to be sure.
