A Japanese deep-water research vessel succeeded in drilling in the seabed at 5,815 meters below the surface of the ocean, a world record for deep-sea boring when remote-controlled cables and drilling tools are used, the government said Monday.

The Ministry of Economy, Trade and Industry said the vessel managed to extract deep-sea sediments in a pipe 4.4 meters long off the Ogasawara Islands in the Pacific in a drilling conducted June 23.

The previous record, set by a U.S. vessel using a similar method, was 2,400 meters, METI said.
