Those posters mean we oppose invitation of Olympicks to Tokyo.
I found them at internet.
I agree with the opinion of those posters.
We can find easily the sites which asserts such an opinion.
I don't recommend that young people come to Japan especially to Tohoku and Kanto areas because I don't hope that they are exposed to radiation.
There are pollutions of the quantity that we cannot ignore in Tokyo.
And furthermore Fukushima Dai-ichi Nuclear Power Prant is discharging 10,000,000 becquerel(Bq) of radioactive materials every hour to the air.
We can't exercise without respiration.
Now some Japanese people want to invite Olympicks to Tokyo without considering such problems.
I desire them to watch reality .
