At the Fukushima Daiichi plant, the Tokyo Electric Power Co., or TEPCO, is struggling to contain the ongoing nuclear disaster. Since the catastrophe almost three years ago, there has been disagreement about whether the plant is safe.

“The government is moving to the forefront and we will completely resolve the matter,” said Prime Minister Shinzo Abe in September, just before Tokyo was awarded the 2020 Summer Olympics.
