Kakomap

Compare a town's past with today in aerial photographs. Using aerial photographs by era published by the Geospatial Information Authority of Japan (GSI), you can overlay and compare how a town looked about 60 years ago with how it looks today. The photographs cover eras from 1928 to FY2007, and you can switch between the eras available at each location.
