When Prime Minister Sanae Takaichi argued before the country’s parliament last month that requiring candidates to disclose prior citizenship would violate “equality before the law,” she framed the issue as one of fairness. In a democracy, however, withholding basic biographical information from voters is not fairness — it is a failure of transparency.
The question is not whether naturalized citizens should serve in public office. In a modern democracy, they should have every opportunity to do so. Many bring international experience, a well-informed world view, linguistic ability and a deep, deliberate commitment to the country they chose to join.
The issue is whether voters have the right to know the backgrounds of the people seeking to govern them. In any healthy democracy, the answer is yes.
Takaichi was responding to questions on May 20 from Sohei Kamiya, leader of the conservative opposition Sanseito party, which campaigned under the slogan “Japanese First” and won 14 seats in last summer’s Upper House election and 13 seats in February’s Lower House election. Kamiya supports mandatory disclosure of prior citizenship by candidates.
The policy debate, however, should not be reduced to partisan positioning. Disclosure is not only about potential risks; it is also about recognizing the full scope of a candidate’s experience. A history that includes naturalization may reflect resilience, adaptability and a conscious embrace of Japanese society. Voters deserve the information necessary to weigh those qualities for themselves.
Japan already asks a great deal of those who seek naturalization. Applicants must demonstrate good conduct, integration into society, respect for the law and commitment to Japan’s constitutional order. In most cases, they are required to renounce previous citizenship — a stricter expectation of exclusive national allegiance than in many democracies.
While Japan does not hold American-style naturalization ceremonies, the principle of allegiance is embedded in the process. Those who become Japanese citizens are, in effect, affirming their commitment to the country’s laws, institutions and civic community.
Against that backdrop, treating prior citizenship as too sensitive for public discussion sends the wrong signal. It suggests that foreign origins are something to be concealed rather than understood. That approach risks reinforcing stigma rather than reducing it.
Other democracies take a different path. In the United States, politicians with immigrant backgrounds often speak openly about their journeys to citizenship. Their stories are not viewed as evidence of divided loyalty, but as proof of commitment and belief in their adopted country. Voters are trusted to consider that information and make informed decisions.
Japan should show similar confidence. Transparency is not discrimination. Disclosure is not exclusion. It is an acknowledgment that voters are capable of evaluating information in context.
Voters already assess candidates based on education,…
