In this study, the authors applied the method of measuring long-term land subsidence by combining DInSAR and time series analysis to Kanto Plains of Japan using ENVISAT/ASAR data. As a result of long-term land subsidence measurement over six years, unambiguous land deformation was detected in six areas: (i) Haneda Airport, (ii) Urayasu City, (iii) Kasukabe-Koshigaya, (iv) Southern Kanagawa, (v) Toride-Ryugasaki, and (vi) Kujukuri in Chiba Prefecture. In particular, the results for the Kujukuri area were compared with the leveling data taken around the same area to verify the measuring accuracy.
