Index maps to Japanese military and imperial maps held at Stanford Libraries. Stanford University Libraries holds a large collection of Japanese military and imperial maps, referred to as gaihozu, or "maps of outer lands." These maps were produced starting in the early Meiji (1868-1912) era and the end of World War II by the Land Survey Department of the General Staff Headquarters, the former Japanese Army. The first charge was to map specific territories beyond Japan's borders. Over time the mapping efforts grew to including "mapping of interimperial boundaries, cadastral surveys of the colonies, and detailed drawings of strategic cities and fortifications." Geographically the Stanford maps cover a broad area including Japan, China, Mongolia, North Korea, South Korea, the Philippines, and beyond.
