Japan is shutting down its last functioning nuclear reactor, with no timetable for a restart.
Reactor 4 at Ohi in western Japan will stop generating electricity in the early hours of Monday.
Analysts say Japan will be without nuclear power until December at the earliest, the longest shut-down since the 1960s.
The Japanese public turned against nuclear power after the meltdowns at the Fukushima plant in 2011.
Before the accident, which was caused by a massive earthquake and tsunami, nuclear plants supplied about 30% of Japan’s power.
But since then the plants have been closed, either for scheduled maintenance or because of safety fears, and have not been restarted.
