To stop the decline in Sado Island's population, the Niigata prefectural government is considering allowing foreign immigrants who wish to live on the island in the Sea of Japan to more easily obtain permanent residency...Niigata Gov. Hirohiko Izumida announced the idea at a prefectural assembly meeting on Friday, and Sado Mayor Koichiro Takano agreed to the idea. The prefectural government has considered giving foreigners permanent residency or long-stay permits with the proviso that they deposit or invest a certain amount of their assets...In Japan, the Immigrant Control and Refugee Recognition Law makes it difficult to introduce such a measure because the law categorizes visa statuses into fields such as official services, arts and education and prohibits visa holders from doing anything unrelated to the fields. In addition, the duration of stay for holders of Japanese visas, except diplomats, is for a maximum of three years per visa, and it is difficult to obtain permanent residency...The Niigata prefectural government will ask the central government to make Sado Island a special district where foreigners can receive permanent residence status with no job restrictions as long as applicants deposit a certain amount of money in Japanese banks.
