The astronomical observation work at the Hydrographic and Oceanographic Department of the Japan Coast Guard( JHOD) was completed in 2008. The astronomical observation work was emphasized as the basis for determining the longitude and latitude necessary for the compiling of nautical charts and hydrographic surveying since its establishment in 1871, and has since been improved and expanded. The astronomical observation work at the JHOD has long contributed to hydrography for a long time, changing its aim from determining longitude and latitude to maintaining the accuracy of the nautical almanacs and using it for geodesy. Ten years have passed since the completion of the astronomical observation work at the JHOD, and the past memorandums of the astronomical observation work at the JHOD, including the history of the each hydrographic observatory and the changes in equipment, are compiled in this paper as a reference for future generations.Journal
