Japanese firms seek domestic offshore gas
Inpex, backed by Jogmec, is set to start drilling off the coast of Japan in March

Officials from Japan’s Ministry for Economy, Trade and Industry—which commissioned the original exploration drilling—have been talking up the potential resource size in the press, while Inpex suggests that, if commercially viable, any finds would “contribute to the improvement of Japan’s energy self-sufficiency rate”. The site is roughly 130km north of the coastal city
