The Japanese have lots of credits on environmental issues: it's one of the cleanest country I've ever seen, so I'm willing to trust them if they say the waste water dumping plan is safe.
Edit: Hey, look, somebody wrote a book with the latin thing I said as its title, whose contents I probably summarized the thesis of without even reading.

I wouldn't rely on that alone. I'd say they are more clean than concerned about ecology. You don't see thrash in streets or in forests, that's true. But their recycling is almost non-existant, they burn almost all the waste. They use (thick) packaging in absurdly high amounts (to an european eye). They have fishery and whaling issues…
The prefectural governments did not publish the results and did nothing in response to these surveys. The participants who had donated hair samples were not informed of their result, even when they requested it”
We're relying on mostly the same people, minus the pragmatic ones who went to bluer skies, to now make trade-offs related to how much Japan's willing to pollute the surrounding seas relative to the economic and politic situation.
