Japan is preparing to update its family registry rules to allow certain regions — such as Taiwan and Palestine — to be listed as places of origin, rather than requiring individuals to select officially recognized countries.

This revision, scheduled to take effect on May 26, brings Japan’s family registry in line with other systems that already permit broader identifications on residence cards.

The ministry insists the measure is a simple administrative change intended to clarify which foreign laws apply in cases like marriage or divorce, though links to sensitive geopolitical issues — like China's fraught relationship with the Taiwanese territory it claims — are unavoidable.

Under current rules, Japanese family registries track births, marriages, divorces, and deaths, primarily for Japanese nationals. However, the registry can note foreign spouses or former nationalities of naturalized citizens.

Japan does not currently recognize Taiwan nationality.

Filipino Nikkei-jin

This is not the first time Japan has taken steps to refine how it categorizes and recognizes foreign nationals. Following World War II, many Japanese living in the Philippines were forced to return home, leaving behind Filipino wives and children, now known as Filipino Nikkei-jin. These descendants often struggled with the loss of their legal status and citizenship rights, sometimes becoming stateless. In an ongoing effort to rectify these issues, the Government of Japan continues to support the Philippine Nikkei-jin Legal Support Center which last year conducted its 18th Survey of Second-Generation Filipino Nikkei-jin.

This survey, running from May to July 2024, involves individual interviews to aid in nationality acquisition, as well as the collection of documents like birth certificates and marriage records.

Japanese Ambassador Endo Kazuya recently met with Philippine Statistics Authority Undersecretary Claire Dennis S. Mapa, Ph.D., and other officials to discuss these measures, highlighting the shared commitment to restoring Japanese nationality to individuals affected by wartime displacement. Both parties also explored potential avenues for expanding Japan-Philippines cooperation in statistical development.
