Nuclear power will continue to satisfy a "significant proportion" of the Japan's electricity demand in the future, despite the nuclear accident caused by last year's disasters, according to the Economist Intelligence Unit, an economic research body affiliated with the Economist magazine.

Martin Adams, energy editor for the think tank, said he detects a more favorable climate toward nuclear power in Japan and a realization that, given the country's scarce natural resources, nuclear energy has a role to play.

He said use of nuclear power in the country will remain at low levels for the next two years due to a mixture of continued inspections of reactors, "foot-dragging on restarts" and the likely decommissioning of some aging reactors.
