Abstract The seismic wave caused by the Great East Japan Earthquake that occurred on March 11, 2011 at 14:46 JST (magnitude: M 9.0, location: 38° 6.2 min N, 142° 51.6 min E, depth: 32 km) was clearly observed approximately 20 min later by the superconducting gravimeter at Syowa Station, about 14,000 km away from Japan. The observation of the free oscillations of the Earth will be reported compared to the observed records of the Sumatra earthquake on December 26, 2004 (magnitude: M 9.1) and Chile earthquake on February 27, 2010 (magnitude: M 8.8).
