Look at the byline:
"Makiko Segawa is a staff writer at the Shingetsu News Agency. She prepared this report from Fukushima and Tokyo. She can be reached at email@example.com"
Look up who the "Shingetsu News Agency" is. Note that they have no real press credentials and their articles, especially those by Miss Segawa fall well into the fear-mongering "OMG!! BIG GOVERNMENT COVERUP!!" end of the scale.
The situation in Fukushima is being watched by nuclear experts all over the world and the basic facts of the aituation are posted on the IAEA's site. Anything beyond the stating of pressure, temperature and radiation readings as well as remediation steps being taken should be taken as pure guesswork. There has been way too much "This could mean that the reactors are undergoing fission and could go critical" kind of speculation.
