Temporal change of the groundwater-related problems in urban areas is summarized based on the experiences in Tokyo metropolitan area. Land subsidence and oxygendeficient air problems were representative ones caused by groundwater over-exploitation in the past. Strict regulations against groundwater extraction have made groundwater potential recovered. On the other hand, higher than expected recovery of the groundwater potential has made maintenance of subsurface structures costly. For the sustainable groundwater extraction and usage, a method to integrate numerical simulation of groundwater flow/deformation coupling processes and monitoring of ground surface movement is proposed. Achievement of sustainable groundwater use in Tokyo can contribute to the mitigation of the groundwater-related problems in the developing Asian mega cities.
