This pictorial map depicts the Abe-kawa<em> </em>River region of Japan, located in what is now Shizuoka Prefecture. The steepness and rapid flow of the Abe-kawa has caused numerous floods in the delta region, and open levees have been built since the Edo period (1603–1868) in order to protect the crop fields and villages. Tokugawa Ieyasu (1543–1616), founder of the Edo shogunate, implemented a major flood-control project and ordered an embankment to be built along the Abe-kawa in 1606, determining the current route of the river. This map is a draft manuscript for an official map, and several symbols and village names are crossed out or written over. The map is color coded according to the landscape and notes important graves, ponds with abundant fish, and sporadic measurements of distance and <em>koku</em> (the volume of rice that the region can yield). The castle of Suruga Province is located in the yellow section at the upper right, and the Ōya <em>kuzure </em>(landslide), origin of the river and site of one of the three largest landslides in Japan, is noted in brown markings on the center of the left edge of the map. The map is oriented with north to the upper left.
