If the Tokyo Olympics are held on schedule, thousands of athletes will soon come to Japan. Considering the multiple reactors that melted down there nine years ago, in March 2011, the government's decision to start the ceremonial torch relay in Fukushima Prefecture seems a bit odd, to say the least.
While radiation levels may have declined since 2011, there are still hot spots in the prefecture, including near the sports complex where the torch relay will begin and along the relay route. The persistence of this contamination, and the economic fallout of the reactor accidents, should remind us of the hazardous nature of nuclear power.
Simultaneously, changes in the economics of alternative sources of energy in the last decade invite us to reconsider how countries, including Japan, should generate electricity in the future.
