The growing share of renewables in the mix doesn't mean there's no place for nuclear in the future – it's a false dilemma fallacy. Also, Japan's solar panels may be visually imposing, but they constitute a tiny amount of total energy generation in Japan.

After Fukushima Daiichi disaster Japan shut down all it's reactors and switched to fossil fuels, not renewables, and this is the most tragic outcome of the disaster.

Neither nuclear nor renewables could entirely replace fossil fuels, we desperately need both. Hopefully Japan is restarting it's nuclear reactors (5 reactors were restarted in 2018) and investing in renewables, but I'm afraid it's still not enough.
