Oizumi Town in Gunma, where foreigners make up 20% of the population, was often mentioned as an example of "peaceful co-existence between Japanese and foreign residents." Following the rise of Sanseitō and PM Takaichi's pledge to review immigration policies, the town's political climate has changed.
One catalyst was the July House of Councillors election. In Oizumi, the Sanseitō's proportional representation vote share was 15.6%, surpassing the national average of 12.6%. In the single-seat constituency, the Sanseitō candidate topped the polls in the town, outnumbering the ruling Liberal Democratic Party candidate. The rise of the Sanseitō could alter Oizumi's image as a city successfully coexisting with foreigners. Mayor Murayama Toshiaki, who has focused on "co-existence" with foreigners since taking office in 2013, expressed surprise at the election results.
In 2024, nearly three in ten babies born in the town—28.9%—were foreign nationals. Among Japanese residents, the largest age group was fifty to fifty-four, while among foreign residents, it was twenty-five to twenty-nine. This younger demographic has brought energy and labour strength to the community, helping sustain its local economy.
Since 1986, the town's total population has grown by almost 12%—a rare trend for municipalities of its size—though the number of Japanese residents alone has fallen by over 11%. At present, forty-seven foreign workers are employed in local care facilities, and that number continues to rise. Murayama observed that without them, there would be few people left to care for Japan's ageing and bedridden citizens. He added that Oizumi, often viewed as a symbol of Japan's demographic future, had long worked under the belief that its own experience offered a glimpse of what the country as a whole would soon face, and that the community must keep striving toward genuine co-existence.
