Six hundred and sixty-two gravity data have been newly obtained from a dense gravity survey in and around the Toyama Plain. The Bouguer anomaly map, drawn from a total of 931 gravity data including the 662 new data, has revealed some prominent underground structures of the Himi and Isurugi faults. Both faults have the same NE direction, nearly the same length of 15-20 km, and a similar steep gravity gradient of about 15 mgal/2 km on the new Bouguer anomaly map. Unlike the Isurugi fault that characterizes the western boundary of the Toyama Plain, the Himi fault shows neither clear topographic lineaments nor large fault zones. Since the Himi fault is covered by Pliocene and Quaternary sediments, it is not an active fault but is likely to have finished its main activity before the Pliocene.
