This map was reportedly produced by Kageyama Chikyo in "Ansei 3" or 1856. The map shows the Sumida area which is one of the 23 special wards of Tokyo. It is in the northeastern part of Tokyo and is bounded by the Sumida and Arakawa rivers. This colorful woodblock pocket map folds into hard paper covers in bright blue with a paper label on the front. Travel and tourist maps are called dochuzu or "on-the-road-maps".

This map is mint with fine color and sound paper, less one tiny worm track and two short fold intersection splits as often seen with these maps. The covers are likewise fine but the back cover has a short thin line or worm track affecting blue color.
