Kaido Ziółkowska, formerly known as Kaido Nakamura, currently holds the esteemed position of the First Lady of the Polish Social Nationalist Republic. Born in Kyoto, Japan, she resided there until her relocation to Tokyo to pursue higher education. In 2024, fate brought her into contact with Hubert Ziółkowski during his tenure as the Polish ambassador to Japan, leading to the development of a deep connection that eventually blossomed into a committed partnership. Following Vlasov's invitation to form the Union of Nationalist Parties, Ziółkowski returned to Poland in 2024, with Kaido accompanying him. Later that year, they solemnized their union in matrimony.
Kaido formally affiliated herself with the Union of Nationalist Parties and subsequently the Social-Nationalist Polish People's Party. Although not politically active herself, she has consistently provided steadfast support for her husband's political endeavors, often advocating for his positions. Moreover, she has played a crucial role in fostering Polish-Japanese cultural exchanges, particularly before the change in Japan's government. Kaido has also been instrumental in organizing and nurturing the Japanese diaspora in Poland, which thrives notably in Ziółkowskigród and Warsaw. While it has been speculated that she may hold more progressive viewpoints privately, Kaido has not disclosed her personal beliefs to the public.
One notable aspect shared between Kaido and her husband is their proclivity for alcohol, with some suggesting that they may verge on or have already reached alcoholic tendencies.
