Japan's taxpayers also happen to be Japanese people employed in these companies, so they get their share of that revenues. And the price doesn't even account for the taxes that are paid back to the government directly.

Japanese wages are notorious for being lower that a lot of the developed world and there is a problem with stagnant wage growth.

I don't think there is any need to try justify a screw up on this level as being good. Fukushima was a disaster, economically and for the image of nuclear globally.

Nobody said otherwise, you are desperately moving the goalpost here.

“Desperately”, you’re a funny guy. I live in Japan, no tax payer here is sitting around going, “how wonderful the nuclear disaster was, now we’ll get all this new tech to boot”.

Sometimes you need to call a spade a spade. This was a disaster, politically, economically and environmentally. Yes some good will come from it, but ultimately, it was better off not happening. All that money could’ve and should’ve went on new and safer power plants.
