The government must do more to protect Japanese-Brazilian workers who have been severely affected by the protracted recession, Japanese and Brazilian scholars said at a symposium held Tuesday in Tokyo.

During the symposium, organized by the Foreign Ministry, academics said the financial plight of Brazilians in this category has extended the average length of their stay here.

Brazilians of Japanese descent, who are legally allowed to engage in simple manual labor in Japan, began flocking to the country in the mid-1980s.
