In recent years, we conducted marine seismic surveys in the Japan Sea with the research vessels of the Japan Agency for Marine-Earth Science and Technology (JAMSTEC). In these surveys, high quality bathymetric data by the multi-narrow beam echo sounder have been obtained simultaneously with navigation of vessels. Bathymetric data are one of the important key to understand tectonic history and earthquake source fault model in the Japan Sea. Therefore, the effective use of high quality bathymetric data makes progress in the integrated study of the relationship between active structure, seismicity, and crustal structure in the Japan Sea. In this report, we describe about red relief image map and DEM (Digital Elevation Model) data which are created by the integration of topographic data in and around the Japan Sea.
