1. Although there are some investment immigration plans in Japan, these plans usually require investors to invest a certain amount in Japan and create a certain number of employment opportunities in Japan.

These plans have some specific requirements and standards, which can't guarantee that all investors can get green cards. For more information about the investment immigration plan, please consult the Japanese Immigration Bureau or the relevant immigration lawyer.
