Several characteristics are unique to historical Japanese maps. First, only Japan created maps on ceramic plates. Second, Japan was willing to fully integrate European map-making techniques. These might include a grid of longitude and latitude, a compass rose, the circle or decorative device printed on a map showing the points of the compass, copperplate printing, or information taken directly from European maps or European-style land surveys. A third feature is the maps’ orientation. Some Japanese maps are labeled to the outer edge in all directions. In other words, they are created to be viewed from any side. No view is prioritized, which is likely a direct result of historically viewing maps on the floor. This worm’s-eye perspective means the viewer is meant to enter the map as if one is standing in the center and looking outwards in every direction.
