Tokyo 
One thing I should point out about the Thursday/Friday warning is where it sits on the impact matrix. If it gets any more certain then it will trip into the amber part of the matrix. Theoretically it could warrant a red warning eventually. But they are issued with great thought and consultation.
Remember it is an impact matrix, so it isn't based on snow depth, but rather the potential for how much impact it could have on travel, health and energy security. If weather is going to just affect a few poor sheep, then they don't get the same sort of impacts as if it hits a major city.
