The Geological Survey of Japan started a geological mapping project in Japan in 1882. This paper summarizes the historical transition of the strategy of the geological mapping project, which coincides with the transition of the overall scenarios of the mapping project in Japan. Each geological map has an individual scenario on which integration of research elements is conducted. Each individual scenario depends on local geology. 1:50,000 quadrangle geological map is the most basic one developed in the Geological Survey of Japan, and I discuss the mapping project in terms of the overall and individual scenarios.
