An
Alien Registration Card (
gaijin toroukushou) is
issued by
city governments to
aliens living
in
Japan. The card has a picture of the
gaijin,
the
gaijin's name, address, date of birth,
place of birth, nationality, and
fingerprint.
Foreigners are required to carry their
alien
registration cards
at all times, and must produce
them on demand if asked by a
police officer.
If you want to buy a
keitei denwa (
mobile phone),
you need to show the
shopkeeper your
card.
