This Ad fontes tutorial introduces students to Japanese maps from the eighth to the nineteenth century. Students learn about different types of maps, as well as the political, economic, and social conditions from which they emerged. Exercises allow students to read and interpret several Edo-period maps and to edit old maps with Digital Mappa, a text editing tool, especially conceived for old maps. Additional resources explain map typologies, calender systems, and offer instructions on how to use databases and digitized map collections.
