The Japanese vessel Chikyu started drilling in waters about 1000 meters deep, some 70 to 80 kilometers off the Japanese coast in February 2012. The vessel will dig about 260 meters or more below the seabed to reach the methane hydrate.
The drilling is part of a two-year program commissioned by the Japanese Ministry of Economy, Trade and Industry for testing and data collection. Continuous production of methane is planned over several weeks in January to March 2013.

Has there been any further advancement in this subject? I haven't found any results from the japanese drilling online.
