The bill is widely interpreted as a way of preventing sensitive information about Fukushima (among other topics) reaching the Japanese public and by extension
the rest of the world.

The independent organisation Reporters Without Borders has downgraded Japan in its world press freedom index from 22nd place in 2012, to 53rd in 2013 and
to 59th in 2014, following the passing of the state secrets bill. Reporters without Borders say that Japan“has been affected by a lack of transparency
and almost zero respect for access to information on subjects directly or indirectly related to Fukushima”

All 23 districts of Tokyo contaminated with radiation, worse than at Chernobyl after the accident, and blood cells of children under ten are showing worrying changes; the WHO, the IAEA & the Japanese government cannot be trusted.
