Abstract
During the years 2005-2007, we developed the national project "Science and Technology Literacy for Morally Well-Off Life in the 21^<st> Century". The goal of this project is to show what basic knowledge is to be shared by all Japanese citizens in order to have a sustainable democratic society, in which everyone will be respected as an irreplaceable constituent, and everyone may participate in the decision-making of society on the usage and direction of science and technology issues so that the globe and mankind are sustainable. Presented here is a summary of the report "Integrated Report of Science and Technology Literacy for the 21^<st> Century", which concerns not only natural science and technology, but also social science, because for a real understanding of the world, integrated knowledge of natural and social science is needed.
