To answer the original question, it has nothing to do with bragging rights or records. While it might come as a shock to some people, the United States is hardly the center of the universe. Japan is a hugely populated country, about half the population of the US. Like any park in the US, Spaland wants butts in the park.
I must have closed or nuked a dozen threads on CoasterBuzz talking about how Steel Dragon will "suck" and it "can't be better" than Millennium Force. If Morgan's engineering is sound, I'd bet that it will be a better coaster. Who cares?
