Concerns regarding nuclear power in Japan following the accident at the Fukushima No. 1 nuclear power plant are fueling debates on a possible reformulation of the country's energy policy.

While a complete transition from the current energy mix would not make economic sense, the government needs to take into consideration the geographical vulnerabilities of Japan's nuclear power plants and public sentiment against them.

The decision to shut down the Hamaoka nuclear power plant due to growing concerns over the seismic risks of the location is certainly understandable. It could, however, have a rippling effect on the domestic front and the government may face economic challenges if power shortages arise.
