Japanese immigration will start scanning fingerprints and taking photographs of foreign visitors like USA does, as a part of anti-terrorists law updates. This law seems to become effective next week.
Well, they decide/update laws like this while we're all not aware of (-- and they do a lot. Everytime we have elections the theme is some bullshit stuff like "Making Postal Office a private company" or "How to compensate lost pension notes")
Anyway, having FP scanned and face photo taken is one of the most gross and annoying experience at airports. When I come back to USA and go through the security process, I always feel that I'm not welcomed. Already feeling sorry for what all travelers feel in Narita.
