Outline of the Survey
Purpose and History
The Report on Internal Migration in Japan Derived from the Basic Resident Registration aims at providing data on internal migration of the Japanese and foreign people based on the records of the Basic Resident Registration which the mayor of each municipality (shi, ku of ku-area of Tokyo, machi and mura) is responsible for preparing in accordance with the Basic Resident Registration Act.
This report started as the "Report on Internal Migration in Japan Derived from the Resident Registers". Resident Registration Law (Act No.218 of 1951) was renewed to the Basic Resident Registration Act (Act No.81 of 1967). Therefore this report also changed its name to the "Report on Internal Migration in Japan Derived from the Basic Resident Registration".
* With the enactment of the Law for Partial Amendment to The Basic Resident Registration Act in July 2012, foreign residents are also covered by the Basic Resident Registration Network System from July 8, 2013. This report includes a person having no Japanese nationality provided for by the Basic Resident Registration Act.
