I visited Niigata prefecture to see biological impacts of Fukushima Daiichi nuclear power plant accident. Niigata prefecture is famous for ski and snowboard resort. I visit there to play snowboard every year.
In spite of the accident, foods and water of Niigata prefecture have no radioactive materials (http://www.mhlw.go.jp/english/topics/2011eq/level_jan21.html).
High mountains of the prefecture prevent radioactive materials from the site. So, it is known as clean land which has no contamination at all (http://www.pref.niigata.lg.jp/HTML_Top3/169/293/Ver2(en).pdf).
It seems that people in Niigata prefecture have no worry about the accidents because they have no biological impacts by the accident.
So, we can play snowboard or ski safely.

I am continuing to visit various places in Japan to see the effects of the accident because I can see people as well as many creatures which are sensitive to radioactive materials from the environment. It is important to see their health for our safety.
