(TEPCO), in Okuma, Fukushima Prefecture, northeastern Japan, one month before Japan marks the fifth anniversary of a devastating earthquake and tsunami that left nearly 19,000 people dead or missing, turned coastal communities into wasteland and triggered a nuclear crisis. A cost estimate to clean up Japan’s wrecked Fukushima nuclear plant has doubled to nearly 22 trillion yen ($190 billion), with decommissioning costs expected to continue to rise, according to a government panel Friday, Dec. 9, 2016.
