Japanese Prefecture Codes - CSV
The Japanese Prefecture Code is a two-digit numerical code system defined by JIS X 0401 for identifying Japan's 47 prefectures. It was introduced in 1968 by the Ministry of Home Affairs (now the Ministry of Internal Affairs and Communications) to streamline administrative processes. The codes are assigned from 01 to 47, generally following a geographical order from northeast to southwest, with Hokkaido as 01 and Okinawa as 47. This coding system has been adopted as ISO 3166-2:JP and is widely used as an international standard for identifying Japanese regions.
