The article doesn't state this, but how much were they overstating it by? 1%? 10%? From the article, it looks like the error is due to some smaller companies reporting wrong numbers, either due to incompetence or malice / fraud. I'm guessing the final country-wide numbers may be off by something like 1% instead of 10%, which is an error, but not going to wildly change Japan's GDP.
