In this article, the mid-long term energy balances in Japan taking account of the Great East Japan Earthquake was studied. Three major risks that may occur around 2050 were considered. The major risks were low acceptance for nuclear, CO2 constraint and shortage of oil and gas. It was concluded that the development of various energy technologies such as energy saving, renewable, nuclear and fossil fuels should be promoted to manage the major risks especially for the long-term energy balances. Hydrogen related technologies have a large potential to contribute to manage the major risks.
