History buffs can now take a stroll through the Tokyo of the past with this new app, which overlays classic maps of the city onto modern ones and points out historical sites via GPS.

Similar apps have been released before, but this one improves on common problems, such as unmatched topography and hard-to-read characters. It uses a completely redrawn map, making it easy to superimpose the historical and modern versions. In addition, you can compare the two with an adjustable transparency function.

The app, created by East Japan Marketing and Communications, Inc., JAF MEDIA WORKS Co.,Ltd., Seiei-Anime Co., Ltd., BeMap, Inc., and Fuji Television Network, Inc., is available on both iOS and Android.
