The change of land use was greatly influenced by the construction of facilities and the preparation of a network of roads related to the Winter Olympic Games. Especially, cancelling the designation of agricultural land zone by the administrative agency and the public conversion of agricultural land have quickened the urban sprawl in Nagano City. Cancelling the designation of agricultural land zone and conversion of agricultural land were performed without consideration of land use planning for the while city, and the control of land use thereafter was not done properly. A comprehensive system of land use all over the city is necessary.
