Well, to start almost everything in Japan is paved over. Also, outside of carting away rubble, they didn't really clean up any radioactive materials. Most of the worst of it was gone after the first two months. The rest kind of just got spread around.
On a side note, Japan doesn't have zoning laws that keep polluting businesses away from the population centers. So try and guess where Hiroshima is without looking it up.

Cancer rates all over Japan are wonky.

both nukes were detonated at low altitude below 2000 feet to maximize overpressure blast radius @5psi.

I expect that Japan is probably some sort of cabal testing ground for giving people cancer.
cracka please, you said a few. If you knew English that means three or four.
Also I'm a different dumbass correcting your mistakes, not saying you were wrong.
