This article highlights the national security risks posed by dual citizenship legislators, first-generation naturalized politicians, and foreign secretaries within Japanese politics. Drawing from Takufumi Genkotsu’s analysis, it exposes cases involving Chinese connections, potential espionage, and political actors who oppose policies vital to Japan’s national interest. The piece argues that Japan must restrict dual citizenship in parliament, limit candidacy for naturalized individuals and those with foreign spouses, and safeguard government access from foreign influence.

The following is a continuation of the previous chapter.
The facts revealed in this article would never have been known to Japanese citizens who only subscribe to newspapers such as the Asahi Shimbun and watch television stations that are their subsidiaries and monopolize terrestrial broadcasting, including NHK.
Information leaking directly from politicians.
It is still fresh in our memory that during the Democratic Party leadership election, a dual citizenship issue arose concerning candidate Renhō.
As Rikiō Kōzu, president of RENGO, stated, “There are other members of parliament with dual citizenship,” and “There is no need to make a big fuss,” it is noteworthy that the mass media and others are actively defending such cases, even though the Nationality Act clearly defines dual citizenship as illegal.
The Japan Innovation Party submitted a bill to prohibit individuals holding any foreign nationality from becoming members of parliament or national public servants.
It is difficult to understand why there are differences in attitude among political parties toward such an obviously reasonable move.
Allowing individuals with multiple nationalities to have the right to stand for election creates a high risk of a “conflict of loyalty,” especially in fields related to national security where national interests may collide.
It is an issue that should be addressed promptly.
Sumio Mabuchi, election campaign committee chairman of the Democratic Party, stated that “there seem to be a dozen or so” members of parliament currently in a dual nationality state.
The Renhō case is only the tip of the iceberg.
All the pus should be exposed.
In addition to the dual citizenship issue, what is even more serious is the problem of first-generation naturalized legislators and foreign secretaries.
For example, a certain Democratic Party legislator was originally a Chinese national before naturalization.
It would be fine if he, after naturalization, promoted policies beneficial to Japan, but he supports foreign residents’ voting rights and hate speech regulation laws, and opposes the Specially Designated Secrets Protection Act and security-related legislation, demonstrating a firm stance against policies that protect Japan’s national interests.
Another example is the former Democratic Party member Mari Kushibuchi, whose husband is a Chinese man named Li Song.
According to former police officer Tadanobu Bandō, Li Song operated a group called the “Japanese Spouse Support Association,” which coached Chinese women on how to remain in Japan illegally.
Bandō also questioned how Kushibuchi, whose husband is supposedly a Chinese democratic activist, was able to join a 2009 delegation led by Ichirō Ozawa to visit China, suggesting that Li Song might be a Chinese spy posing as a pro-democracy activist.
In the 18th unified local elections, Li Xiaomu, who had been naturalized only two months before the election, ran for office in the Shinjuku ward assembly election (and later lost).
Given the current climate in which decentralization and foreign residents’ voting rights are increasingly promoted, close attention must be paid to local politics just as much as national politics.
Members of parliament and local assembly members possess the authority of national and administrative investigation, allowing them to access classified documents of the state and local governments.
To protect Japan’s safety and peace, not only should dual citizenship legislators be prohibited, but individuals who are first-generation naturalized citizens or whose spouses are foreign nationals should also be barred from running for office.
Additionally, the appointment of foreign secretaries should be restricted, especially regarding individuals from China, North Korea, and South Korea—countries that do not share Japan’s values.
