It has been confirmed that the Japanese government secretly reviewed a worst-case scenario plan of evacuating more than 36 million people after the nuclear disaster last March at the Fukushima Daiichi nuclear power plant.

An internal Japanese government report details that Tokyo reviewed a plan to order evacuations for residents in areas within a 170-kilometer radius of the nuclear power plant if the nuclear disaster had been uncontrollable.

Under the plan, the Japanese government would have also recommended people living in regions within a 250-kilometer radius of the power plant to voluntarily evacuate.

The emergency evacuation plan included not only Fukushima but also Tokyo and its neighboring regions.

The internal report expressed concern that danger could remain in the contaminated regions for decades.

The document was written by Japan’s Atomic Energy Commission and reported to then Japanese Prime Minister Naoto Kan on March 25th, two weeks after the Fukushima nuclear disaster occurred.
