Japan’s offer, extended to hundreds of thousands of blue-collar Latin American immigrants, is part of a new drive to encourage them to leave this recession-racked country. So far, at least 100 workers and their families have agreed to leave, Japanese officials said.

Under the emergency program, introduced this month, the country’s Brazilian and other Latin American guest workers are offered $3,000 toward air fare, plus $2,000 for each dependent — attractive lump sums for many immigrants here. Workers who leave have been told they can pocket any amount left over.

The program is limited to the country’s Latin American guest workers, whose Japanese parents and grandparents emigrated to Brazil and neighboring countries a century ago to work on coffee plantations.

In 1990, Japan — facing a growing industrial labor shortage — started issuing thousands of special work visas to descendants of these emigrants. An estimated 366,000 Brazilians and Peruvians now live in Japan.

“There won’t be good employment opportunities for a while, so that’s why we’re suggesting that the Nikkei Brazilians go home,” said Jiro Kawasaki, a former health minister and senior lawmaker of the ruling Liberal Democratic Party.

“Nikkei” visas are special visas granted because of Japanese ancestry or association.
