Japan's ruling Liberal Democratic Party has formally proposed making the country's My Number identification cards mandatory for all residents, reigniting a contentious debate over digital governance and individual privacy rights in one of the world's most technologically advanced democracies.
The proposal, announced Tuesday by LDP policymakers, would end the voluntary nature of the My Number system that has defined it since its troubled launch in 2016. Under the plan, all Japanese residents would be required to obtain the IC chip-embedded card that links an individual's tax records, social security information, and increasingly, healthcare data into a single government database.
"This is about administrative efficiency and preparing Japan for the digital age," an LDP policy official told reporters, speaking on condition of anonymity. The government argues that mandatory adoption would streamline public services, reduce bureaucratic redundancy, and save taxpayers billions of yen annually.
Yet the push comes at a delicate moment. The My Number system has been plagued by implementation problems since its inception, including multiple high-profile data breaches, cases of cards being mistakenly linked to wrong individuals, and widespread public distrust. As of April 2026, only approximately 75% of eligible residents had obtained cards despite sustained government campaigns promoting their use.
Privacy advocates have pushed back sharply. Taro Yamada, director of the Tokyo-based Digital Rights Forum, described the mandatory proposal as "a fundamental shift in the relationship between citizen and state."
"In democracies like Germany, France, and Canada, national ID systems exist but are implemented with robust privacy safeguards and transparent oversight mechanisms," Yamada said. "Japan's system lacks these protections. Making it mandatory without addressing these structural problems is putting efficiency before rights."
The comparison to other developed economies is telling. introduced mandatory ID cards in 2010 but built in strict data protection rules and limited what information could be stored centrally. abandoned a similar scheme in 2010 after massive public opposition. has a long tradition of national ID cards, but recent attempts to digitize and centralize data faced fierce resistance from privacy groups and the courts.
