$200 sign up bonus? It always gives a bit of whiplash looking at US cards after looking at Japan cards. The big sign up bonuses in America just never happen here at all, nor the big 5% rewards. I can get points on my Japanese cards but it's only like 1%. I'm sure network fees or something I don't know about is at least partially responsible for the difference, but it's always pretty shocking to see.
I honestly don't even pay attention to it too much. Most of those cards have such huge interest rates it's an immediate turn off for me. Even though I pay must stuff off on time now I still don't like that threat looming out there.
