The Bouguer anomaly distribution in and around Japanese Islands has been analyzed for the study of the crustal and upper mantle structures. Regional value of gravity anomalies has been adopted intending to remove unknown effects of various kinds which would obscure the regional structure. In the first stage of the treatment, the Bouguer anomalies Δg for 1° squares have been calculated from the map compiled by Tsuboi and then reduced by ""influence coefficient method"" to obtain the reduced Bouguer anomalies AG. The reduced Bouguer anomaly could be regarded as the mean gravitational attraction over a square when the structure just below the square is assumed to extend to infinity. This enables one to estimate the depth of the Mohorovicic dis...
