Japan started fingerprinting and photographing arriving foreigners Tuesday in a crackdown on terrorists, despite complaints that the measures unfairly target non-Japanese. Nearly all foreigners age 16 or over, including longtime residents, will be scanned. The only exceptions are diplomats, government guests and permanent residents such as Koreans who have lived in Japan for generations. Tokyo has staunchly backed the U.S.-led attacks on Iraq and Afghanistan, raising fears Japan could be targeted by terrorists. Officials said the new security measures, while inconvenient for visitors, were necessary.
