Juminhyo is a resident registration system in Japan that records the personal information of individuals living in a specific area. It includes details such as name, address, date of birth, and family relationships. This system is essential for various administrative purposes, including voting, taxation, and access to public services. The Juminhyo is maintained by local governments and is updated whenever there are changes in a person's status, such as moving to a new address or changes in family composition. Citizens can request a copy of their Juminhyo for identification or official purposes.
