I posted this on my Facebook, on 11 March around midnight, a few hours before leaving Tokyo.

As I was walking the street after a meeting at the Ministry of Agriculture and Fisheries in Tokyo yesterday morning and passed the Ministry of Energy, Trade and Industry (the famous METI), I spotted the anti-nuclear tent installed there and maintained by Japanese activists for 1643 days (if my calculator is correct, that's 4.5 years).
I stopped and chatted for a few minutes with the activists on shift.

This action alone is not going to resolve the issue it addresses (of course).
But one thing you can say of anti-nuclear activists is that they are as persistent as Plutonium.
And this is good.
