The ruling Liberal Democratic Party's special committee on foreign workers proposed Tuesday that the government set stricter regulations for foreign nationals of Japanese descent when they renew their visas.

Holders of the Japanese ancestry visa can renew the three-year permits almost unconditionally. But under the new proposals, foreigners with Japanese blood would have to have regular jobs, speak Japanese and prove they are paying into social security.

The committee also urged the government to provide more chances for the children of foreigners to learn Japanese in public schools.
