How has Japan's policy regarding Taiwan's recognition in official documents changed?

Japan now allows Taiwan to be listed as a place of origin in its family registry, enabling Taiwanese individuals to express their regional identity distinct from China. This policy change, implemented from May, maintains Japan's consistent position of regarding Taiwan as a region rather than a country, a stance held since 1972 when Tokyo normalized relations with Beijing. While respecting Taiwanese regional identity, Japan's Justice Ministry clarified that this administrative change aligns with their long-standing diplomatic framework. The decision has been welcomed by Taiwan but strongly opposed by China, which views it as challenging their One China principle.
