Thank you for commenting on this :)
I remember Sho-san said, after his very first report on Fukushima, that as the work is far from being done, there's no way he cannot come back, people have to witness what's happening (because nit's so easy to show it when it's a burning subject and then just forget about it), everyone is entitled its opinion of course, but you must be knowledgeable about the subject first. I think that's the main reason he's doing this work, explaining the facts (that's the point of Ichimen) so you can make your opinion.
And I admire him very much for this!
