NARITA, Chiba Pref. — Japan began fingerprinting and photographing foreigners arriving in the country Tuesday under a revised immigration law to keep terrorists out, drawing criticism from rights groups and foreign residents that their data might be abused.

The process at Narita airport, on the first day at least, saw few problems or delays.

The revised Immigration Control and Refugee Recognition Law, which cleared the Diet in May 2006, requires all non-Japanese aged 16 and older entering the country, including those with permanent resident status, to provide their biometric data.
