Abstract
Up until now, a problem for disaster-response measures has been that they have been government-initiated in one direction, from government to citizens, and that there are limits to the government's ability to collect information and ascertain citizens' needs. In recent years in Europe and the United States, measures by ICT use for open government have been pursued aiming to realize open government through citizen participation and collaborations between the government and citizens. In this paper, the effectiveness and problems of the government-initiated measures that were considered at the time in response to the Great East Japan Earthquake, and also of non-government measures by citizens and other groups, are clarified. This paper clarifies the possibility of complement to these problems by applying this approach to disaster response and preparing disaster-response measures on a daily basis that envisages collaborations with citizens. And this paper proposes the necessary specific measures in the future.
