Ezu, (絵図, roughly “picture diagram”) were not necessarily geographically accurate depictions of physical landscape, as is generally associated with maps in modern times, but pictorial images, often including spiritual landscape in addition to physical geography. Ezu often focused on the conveyance of relative information as opposed to adherence to visible contour. For example, an ezu of a temple may include surrounding scenery and clouds to give an impression of nature, human figures to give a sense of how the depicted space is used, and a scale in which more important buildings may appear bigger than less important ones, regardless of actual physical size.
