Wow, Yomiuri/Mainichi are off by a factor of 1 million compared to Sankei. And if I am understanding the numbers correctly, neither of them seem to match the official NISA releases (English or Japanese versions).
What's going on here?

I think it's a given that stupid reporters at at least one newspaper can't tell the difference between a cubic meter and a milliliter. But if the government is releasing wrong readings to begin with, we can't even hope for the news organizations to get it right.
