About the Social Security and Tax Number System (“My Number System”)
Starting October 2015, a twelve-digit individual number (“My Number”) has been assigned to all registered residents (including foreign students and middle-/long-term residents with a visa period of residence of more than three months, as well as special permanent residents who have completed resident registration in Shinjuku City). The use of “My Number” for social security, taxes and disaster countermeasures began from January 2016. Using the “My Number” system will make it possible to confirm whether the information each institution has concerning a particular individual is the same individual.
Thus, various administrative institutions will be able to refer to or provide individual information necessary for various procedures, making administration even more convenient and efficient, and creating a fair and just society.
