Japan, which imports almost all its energy, produced gas in the world’s first tests to extract the fuel from methane hydrate deposits under the seabed, Japan Oil, Gas & Metals National Corp. said in an e-mailed statement.
Gas was produced during drilling today in the Nankai Trough about 50 kilometers (31 miles) off the coast of the country’s main Honshu island, the government-affiliate known as JOGMEC said.
