I have no objection to being fingerprinted at airports when re-entering Japan because I and other foreigners in Okayama suspect that we are being stalked by yet another foreigner who may have a double identity, and it could be that only fingerprinting can establish that person's true identity.
If Japanese citizens, in whose country I am privileged to reside, feel safer if all foreigners are fingerprinted, so do I. The only problem I have when re-entering the country from abroad is the length of time it takes to be processed; but my airline negotiates a special facility because of my age.
