This paper summarizes the efforts made towards mitigating geo-hazard in Shikoku Region due to the Nankai Earthquake within a few decades. At first, it introduces the characteristic features of alluvial deposits in Tokushima and Kochi plains. Being deposited in thick layers, these alluvial plains have greater potential for extensive damage during the Nankai Earthquake. Secondly, it introduces plans of Shikoku Regional Development Bureau and Shikoku Branch of West Nippon Expressway Company towards mitigating the earthquake hazard. Finally, the state of development of countermeasures towards mitigating potential hazard during the Nankai Earthquake under combined efforts of government agencies, private firms, and academic institutions is discussed.
