To promote tourism ahead of the 2020 Tokyo Olympics and Paralympics, the government is considering using Twitter and other social networking services to gauge the pulse of foreign travelers.
By following Twitter, the location of a traveler who comments, for example, "What a view of Mount Fuji!" could be pinpointed so promotional efforts can be focused on that very spot.
On the other hand, tweets complaining about the difficulty of finding a particular museum could be used to determine where to put up direction signs.
