SAO PAULO -- Japan's new residency program for fourth-generation Japanese descendants living overseas did not attract a single Japanese-Brazilian applicant in its first three months.

The program, launched in July, allows descendants ranging in age from 18 to 30 to stay in Japan for up to five years and perform specific types of work. The goal is to ease Japan's labor shortage, and the Justice Ministry initially expected to accept 4,000 people a year. But the Japanese Embassy and consulates in Brazil had not received any applications as of the end of September.

The South American country is home to the largest ethnic Japanese community abroad.

Potential applicants may be put off by the limited period of stay, as well as restrictions on bringing family members along and required certification of Japanese fluency.

The limitations contrast with the rights granted to second- and third-generation Japanese-Brazilians, who are free to live and work in Japan with residency status granted under a 1990 immigration law revision.

Japanese-Brazilian communities are dotted around Japan. Many residents work in the manufacturing sector. But their numbers are in decline: After surging from 170,000 in 1991 to a peak of 310,000 in 2007, the population dropped to 190,000 at the end of 2017 due to a sluggish economy and other domestic factors.

Despite the need for new sources of labor, Japan's government has insisted participants in the program would not be considered immigrants. An organization representing Japanese descendants in Brazil blasted Japan for "treating Japanese-Brazilians, who are their compatriots, as unskilled workers for a limited period."
