As about 83 of Japan is mountainous it causes major pressure on the rest of Japan with its 127 million inhabitants crammed onto only 17 of the island.
Extra-urban impacts of urban activities such as ecological disruption and resource depletion in a citys hinterland and emissions of acid precursors and greenhouse gases. Digital security is another threat cities face when they try to implement smart city projects.
