The landmark Supreme Court ruling in July that found permanent residents of Japan legally ineligible for public assistance is already having an impact. Moves are afoot both at the national and local levels to try to scale back or remove welfare payments to foreign residents.

In a lawsuit filed by an 82-year-old Chinese woman from Oita Prefecture, the nation's top court made it clear that permanent foreign residents do not qualify for public assistance because they are not Japanese nationals. Article 1 of the 1950 Public Assistance Law states the law concerns "all nationals," which the court said referred only to Japanese citizens.

Despite the ruling, the welfare ministry has stood by its long-standing policy of offering the same level of welfare protection to foreigners as Japanese, based on a notice it issued to municipal governments in 1954.
