Last night, I listened to the soothing sound of rain on the roofs in my futon – but I couldn’t get off my mind the thought that winds have been blowing from north-east of Japan all day and would be until Saturday and the night rain was ladden with radioactivity from Fukushima to a certain extent: black rain indeed.

Black rain was the expression used to describe the radioactive fallout after American nuclear bombing of Nagasaki and Hiroshima, before they forced Japan to accept nuclear power. It was later on used as a title for a silly and inaccurate gangster American movie by Ridley Scott. Black refers to the harmful particles in rain drops and is doubly chilling by night time.

Anyway, I slept well but I would like to warn everyone not to stand in the rain until the week-end and especially keep your children dry. Watch out for leaky rubber boots where feet soak for hours, have them wash their hands when coming back home as usual, etc. especially if you are in Aichi (Nagoya) and Kansai (Osaka, Kyoto) areas. Of course, the whole Kanto region (Tokyo, Chiba, Yokohama) is directly under, but nobody should live there anymore.

Contrarily to my post on Shikoku, Fukushima winds avoid it this time, as well as Wakayama according to the Meteocentrale simulation. However, it is only a simulation and daily updates change significantly (usually the last of the 3 days forecast is wrong), so the real situation might change on an hourly basis. Even if this was not the case, there would still be a gap between the simulation and reality. A slight difference means that Shikoku could be swept instead of Osaka since it is after all a small territory. The wind direction has been consistently reported and the higher probability is that the whole Honshu region from Fukushima down to Kansai will get a share of it. (more…)


Sept. 29 Update : New forecast shows that the “monitored region” (Cf. Japan Livability Map September 2011 in SurvivalJapan) was lifted today. No fall-out on Western Japan nor Shikoku today.


SurvivalJapan now exclusively reports on areas referred on the map as “monitored land” and “nuclear-free land”, except for events occurring in the “no man’s land” which may negatively affect the formers. With Chernobyl and Fukushima in mind, you may compare the respective size and distance of Belarus, Germany and Azores in case of doubt about the relevancy of our map. Data used: CRMS Civil Radioactivity Monitoring Stations, Meteocentrale Dispersion Movies for Japan and food supply chain as monitored in the news. (more…)

Radiation dispersion forecast is available from the Switzerland Meteocentrale website.

Contrarily to previous announcement on SurvivalJapan, Meteocentrale uses MEXT data so it is not entirely reliable (Cf. Problematic Japanese Environment Radiation Readings on SurvivalJapan). However, MEXT data only for Fukushima ground zero should be trustworthy.

Here is a screenshot of their radiation dispersion movie for Japan today.

2011 Sept. 9 – Tokyo and Hokkaido are out of the fall-out today as the anticyclone which has been pushing it back is now gone.
