" I guess the radioactive material that is slowly entering the waters there doesn't matter also? "

You are aware I was being sarcastic right? I know you mean well, but sometimes I am not sure.

I think the worst thing is that Tokyo did get the Olympics. Japan/Tokyo has a "host" of problems and "hosting" the 2020 Olympics is going to be an excuse to ignore them. The radioactivity seeping into the sea (and not really that slowly) is exactly one of the problems that will get more short shrift now that we have the Olympics.
