古地図散歩　時代を重ねるマップ

Ever wondered what this place you're walking through looked like in the past? Reflect on childhood memories of the city and parks where you or your parents grew up, or revisit the vacant lot where you played as a child that is now covered with buildings. Explore the changes through the years from the early Meiji era to modern times by looking at maps.

Perfect for strolls, urban explorations, and leisurely wandering, this tool provides a delightful way to appreciate the evolution of different eras. In addition to the basic Google Maps and Geospatial Information Authority of Japan maps, it offers swift surveys from the Edo period, historical maps from various years, and aerial photographs. It covers not only Tokyo but also urban areas such as Nagoya, Osaka, and Fukuoka.

No complex operations are required; easily switch between layers and adjust transparency to suit your preferred style. Thanks to annotations on the base map appearing on historical maps, you can effortlessly enjoy discovering how iconic landmarks like Tokyo Tower appeared in the past.
