Japan seeks new energy supplies
The closure of Japan's nuclear reactors has prompted a hunt for alternative sources of energy in the resource-poor country.
Japan has shut 53 of its 54 nuclear reactors after last year's earthquake and tsunami resulted in radiation leaks at the Fukushima Daiichi nuclear plant.
As a result, there is a wholesale review underway of Japan's power supplies.
Japan is looking at securing supplies from a diversity of sources from all corners of the globe.
Earlier this week, two Japanese companies, Mitsubishi Corporation and Mitsui & Co bought a $2bn (£1.2bn) stake in a liquefied natural gas (LNG) project in Australia.
The BBC's Roland Buerk in Tokyo told Sharanjit Leyl, that the hunt for energy resources is proving very expensive for Japan.
