This is hilarious and infuriating at the same time.
The Japanese government HID the simulation data of SPEEDI and WSPEEDI from the citizens right after the March 11, 2011 start of the nuclear accident, because, as they put it, "(It's so bad that) we can't release it to the general public." Hardly anyone in Japan knew about WSPEEDI until Professor Toshiso Kosako tearfully spoke about it during his resignation press conference at the end of April 2011 and urged the government to disclose it. It wasn't until May 2011 that Ministry of Education very quietly posted the SPEEDI data and WSPEEDI data on its website, without any fanfare.
But as soon as bad and evil North Korea detonated a nuke bomb underground, all government agencies are on top of each other trying to outdo others in disclosing their latest measurements and forecasts. They include Japan Meteorological Agency which banned the agency's researchers to make any radiation measurements or say anything about radiation publicly right after the start of the nuclear accident.
Here's Ministry of Education, extremely quickly releasing (2/12/2013) the WSPEEDI simulation result from the possible fallout (what a joke) from the nuclear testing, using iodine-131 and assuming there was a release (which is very unlikely). The top is for surface level, the bottom is for an altitude of 1,000 meters.
In the meantime, the pork-cutlet-over-curry-rice prime minister believes it is within the definition of "self defense" to attack military installations of a hostile foreign nation and that it is allowed by the current Constitution.
All major news outlets in Japan are busy making a big deal out of the North Korean bomb testing, without shame. They believe Obama's State of the Union address mentioned the incident in a big way.
(Dooon't stop, believin'...hooold on, to that feelin'...)
