A Japanese study estimated that at least 1.1tn cubic metres of methane hydrate exist in offshore deposits. This is the equivalent of more than a decade of Japan's gas consumption. Japan has few natural resources and the cost of importing fuel has increased after a backlash against nuclear power following the Fukushima nuclear disaster two years ago.

The Nankai Trough gas field, located a little more than 30 miles offshore, could provide an alternative energy source for the island nation, reducing its dependence on foreign imports.
