They need cooling water, so “on the coast” is a reasonable location. Or do you mean “not in Japan”? A country without many great options for clean energy generation. Frankly Japan is one of the places nuclear makes sense to me. There’s not many options.

It doesn’t make sense to me in the US where there’s a sunshine belt across the country 5 timezones long, large windswept plains and shallow coastlines. The US is rich in options and nuclear falls down the list.
