In case of a radioactive fallout, it is better not to gather outdoors awaiting further instructions, but to stay indoors. Going to parks is the worst possible idea, because radioactive dust cannot be quickly washed away there. This is probably the true reason why several parks have been closed to the public, according to media reports.
I suppose they will just tell people to stay indoors while they wash the streets - just like it was done in Kiev following the Chernobyl disaster. Once the wind changes direction away from Tokyo, it should be possible to go outside again.
Let's hope this horrible scenario never materializes.
