More than 200 people rallied in Tokyo's Shinbashi district Sunday to protest government-sponsored immigration bills they claim would violate the privacy of foreign residents and strengthen government control over them.

The protesters say the proposed system would allow the government to punish non-Japanese who fail to properly report their personal information, and could even make it possible for immigration authorities to arbitrarily revoke their visas.

The bills now before the Diet "would jeopardize the residency right and right of life (for foreign residents). Therefore, we strongly oppose the bills," said Nobuyuki Sato of Research-Action Institute for the Koreans in Japan, one of the organizers of the protest rally and a meeting on the proposed legal changes.
