Mid- and long- term energy balances of Japan were investigated after the Great East Japan Earthquake on the 11th of March, considering fossil fuel imports, environmental constraints, and economy as well as risks revealed by Fukushima nuclear accidents and disasters. It is concluded that i) great uncertainties on technology and economy are apprehensive about renewable energy oriented energy balance, ii) nuclear power is still an indispensable technological option, and iii) fossil fuels are necessary to meet the balance without both renewables as well as nuclear. The "energy best mix" strategy, which had long been the core philosophy in the Japanese energy policy, should not be amended with the severe nuclear accidents after the Earthquake.
