In many way, social networking in Japan is very much different from social networking in other regions. Mixi, Japan’s largest real identity social network, always had one distinct function: ashi ato, the ability to check which other Mixi user visited one’s profile at which time.
This function, which Facebook, for example, doesn’t offer will be changed next week however: from June 13, Mixi users will only be available who did this in the last seven days. There will be no information on when exactly one’s profile was accessed, and records on visits that happened more than a week ago will get deleted automatically.
This is how Mixi ashi ato will look on PCs (click to enlarge):
