Kuwa-chan’s Decontamination Effort: A Promise with Children

Yutaka Kuwabara, aka Kuwa-chan, used to work as a radiation administrative worker at the Fukushima Dai-ichi nuclear power plant (FDNPP), participating in technical investigation, primary loop recirculation system duct renovation, and detailed checkup of turbine. Also having engaged in natural farming, he used to live in Namie Town, Fukushima, within 20 km of the FDNNP. He and his late-wife, who died of cancer in March 2013, evacuated to Saitama Prefecture shortly after the FDNPP accident following the Great East Japan Earthquake and tsunami on March 11th, 2011. After the accident, Kuwa-chan became so disgusted with how much information was covered up both by TEPCO and the Japanese government that he has grown vocal on Twitter and in his blog, sharing his expert knowledge and educating general public about radiation. He has been going to various parts of Fukushima Prefecture, totally at his own expense, to take radiation measurements and conduct decontamination all on his own.

How a Scientist Was Censored by the Japanese Government After the Fukushima Accident

The following was written on September 20, 2013, for an e-mail communication on some mailing lists, based on the information from the Japanese news and a Japanese blog that summarized a series of Asahi Shimbun articles, called Prometheus Trap: Order to Suspend Radiation Monitoring, published in February 2012.  Although the English version of this Prometheus series is available online, only a limited number of articles can be accessed without monthly payments.
Although this post was not originally intended to be publicized as a blog post, it seemed appropriate to include it here because it is important to address Aoyama's statement in view of his past struggle with the governmental interference. 
***** On September 18, 2013, the Japan Meteorological Agency scientist, Michio Aoyama, told the audience at the IAEA 2013 Scientific Forum "The Blue Planet - Nuclear Applications for a Sustainable Marine Environment," that 60 GBq of Cesium-137 & Strontium-90 directly go out to t…

Is a Study Abroad Program in Japan Safe?

Everyone has to make their own decisions about participating in a Study Abroad Program in current Japan, but here is one female college student's experience.

"I studied abroad in Japan last fall, from late August to late November. I spent the majority of my time in Kyoto, albeit a few weekend trips to nearby cities. My last two weeks in Japan were dedicated to an independent research study, during which I traveled to Tokyo for five days, Nikko for two days and Sendai for two days. While in Nikko, I experienced a constant headache. From there, I took a bullet train through Fukushima up to Sendai. I experienced a severe migraine while traveling through Fukushima by train, and by the time I got to Sendai, I felt fine. I have a history of migraines since Feb. 2009, when I suffered a concussion from a car accident. Despite that, I hadn't experienced a migraine for at least six months before I went through Fukushima. 

Within the three weeks following my visits to Nikko and Sendai…

JFK "Our children and grandchildren are not merely statistics."

The world would be a much better place if all adults shared this sentiment.

Excerpt from President John F. Kennedy's historic speech

Radio and Television Address to the American People on the Nuclear Test Ban Treaty
Washington, D.C.
July 26, 1963

"The number of children and grandchildren with cancer in their bones, with leukemia in their blood, or with poison in their lungs might seem statistically small to some, in comparison with natural health hazards. But this is not a natural health hazard-and it is not a statistical issue. The loss of even one human life, or the malformation of even one baby-who may be born long after all of us have gone-should be of concern to us all. Our children and grandchildren are not merely statistics towards which we can be indifferent."
