Two months after the magnitude-9.0 earthquake and tsunami devastated northern Japan, leaving some 26,000 people dead and causing apocalyptic damage, workers finally entered the reactor buildings at the Fukushima Daiichi nuclear plant.

Nevertheless, a large area of Fukushima Prefecture surrounding the plant remained uninhabitable. Fears surrounding the contamination of local produce and seafood, as well as the stain on Japan’s public image, would likely linger for years.
For all these reasons, Japanese officials ranked the accident alongside the Chernobyl disaster of 1986.
