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 the ocean outside of the Fukushima Daiichi port daily, contradicting the Japanese Prime Minister Abe's words about the contaminated water being blocked from going beyond the port.

It turns out that Fukushima Daiichi's undamaged Unit 5 and 6 take up the Fukushima Daiichi port water for cooling and release the contaminated effluent north of the port, directly into the Pacific Ocean.  This fact, by default, invalidates the Prime Minister Abe's infamous "total block" statement.

Michio Aoyama, a senior scientist at Geochemical Research Department of Meteorological Research Institute, Japanese Meteorological Agency, and a long-time researcher of environmental impact of radioactivity, had his research censored by the government shortly after the Fukushima accident.  First, his team was deprived of funding to check environmental radioactivity almost immediately after the accident and ordered not to take any measurements.  (His team learned of the explosion on TV and immediately began taking samples to take measurements.  The radiation levels were so high that their instruments were not able to take proper measurements, so they were in the middle of making adjustments to enable the necessary measurements when the order came not to take any measurements).  But Aoyama's team ignored the order and continued the measurements with the underground support by other research institutes.  Then Aoyama was told not to release his research findings, co-written by Ken Buesseler and slated to be published in Nature, which stated that the Fukushima oceanic contamination was several orders of magnitude higher than that from the past nuclear testing and at least one order of magnitude higher than the contamination in Black Sea and Baltic Sea due to the 1986 Chernobyl accident.  His superior said to take this part out, which was actually written by Ken Buesseler.  Aoyama could not publish this study due to the Meteorological Agency not giving him permission. 

IAEA's Scientific Forum this year happened to be on radiation and ocean, and Aoyama might have seized the moment to reveal the truth.

However, this does not seem to be taken up by the foreign media.  It might be because this is considered a "routine" release.  However, it does not seem to be a common knowledge amongst the general public that normally operating NPPs release so much radioactivity into ocean/river/lake, so the media might not want to draw attention to it.  In Japan, it became a news item because it directly opposed what the Prime Minister Abe told the International Olympic Committee about the contamination being totally blocked at the port perimeter.

  1. This is beleivable. Abe's assertions not so much.

  2. The Japanese Govt. has become EVIL.

  3. I have lived in Japan for 12 years now and have always had great respect for the Japanese.
    However, the government obviously is corrupt in many ways.
    I believe this has to do with their culture in that they believe if information is unheard of no ones the wiser.
    Meaning the purposely keep and hide information in families, schools and whatnot in hopes that people won't find out.

    Just last night, my parents in-law told my wife and I randomly through a slip in conversation that my wives brother was in the hospital for a minor heart attack 6 months ago. hahahahhahahhah Why? Why was this kept a secret?

    I just wish the government would not keep information and just gives simple important facts.
    With proper news and knowledge people can make their own assessments.

Mako Oshidori in Düsseldorf "The Hidden Truth about Fukushima"

On March 8th, 2014, comedienne/journalist Mako Oshidori gave a lecture, "The Hidden Truth About Fukushima" in Düsseldorf, Germany, organized by a citizen's group, SAYONARA Genpatsu Düsseldorf. Translation of Mako Oshidori's March 6th, 2014 press conference at the German IPPNW (International Physicians for the Prevention of Nuclear War) Symposium in Frankfurt can be found here.
The lecture, given in Japanese with German interpretation, was transcribed and translated into English.

Moderator: Good evening everyone. My name is Mariko. Welcome to a lecture by Mako Oshidori. As we all know, the Japanese people experienced the Great East Japan earthquake and tsunami on March 11, 2011. A huge earthquake, followed by tsunami and the nuclear accident, has become an unprecedented disaster for the Japanese as well as the rest of the world. Moreover, this accident is not only out of control but continues to be in critical state.
As you may be aware, the issue of anti-nuclear power p…

Fukushima Thyroid Examination May 2015: 103 Thyroid Cancer Cases Confirmed, 5 in the Second Round Screening

The Nineteenth Prefectural Oversight Committee for Fukushima Health Management Survey convened in Fukushima City, Fukushima Prefecture, on May 18, 2015, releasing the latest results of thyroid examination, consisting of Initial Screening or the first round screening (originally scheduled to be conducted from October 2011 to March 2014, but actually still ongoing) and Full-Scale Screening or the second round screening (beginning April 2014). It has been 3 months since the last committee meeting on February 12, 2015, and the latest results include 3 more months worth of data confirmed as of March 31, 2015.

An official English translation of the results is now available here.

As of March 31, 2015, there are 16 more (12 from the first round and 4 from the second round) confirmed cancer cases, all papillary thyroid cancer, and 9 more (2 from the first round and 7 from the second round) newly suspicious cases. The number of confirmed cancer cases now totals 103 (98 from the first round and 5…
