The state of race
As the campaign enters its final week, both ruling and opposition party leaders are showing signs of anxiety about Sanseitō’s surging support. The party threatens to disrupt every party in different ways. For the LDP, the party could peel off right-wing LDP supporters, particularly in single-member constituencies; for Komeitō, Sanseitō is exploiting the party’s relative decline and could unseat incumbents in multiple constituencies; for the Democratic Party for the People (DPFP) and Ishin no Kai, the party is a contender for many of the same anti-establishment voters; and for the CDP and parties further to the left, the party’s rise is a source of deep anxiety about the direction of Japanese society and the rise of anti-foreigner sentiment.
A Mainichi Shimbun report on the race in Fukuoka and Kyushu more broadly shows these dynamics at work in a region that has been an LDP stronghold. Sanseitō could be threatening Komeitō’s hold on the third seat in Fukuoka prefecture, while blocking the DPFP from taking it. Meanwhile, the party’s strength in single-member prefectures in the region could be at the expense of LDP candidates, which could largely be to the benefit of the CDP and opposition-backed independents in the prefecture’s races. These dynamics can be found in prefecture after prefecture, across the country, with particularly desperate struggles for the marginal seats in the multi-member constituencies.


While Sanseitō’s rise may be the single most-discussed story of the campaign, the inexorable decline of Komeitō could be at least as important in its implications. The party’s national PR vote totals have been steadily falling, but it increasingly appears that this election could be the one in which the party’s sputtering electoral machine has real consequences for the ruling coalition. If the party does not have enough strength to hold the seats in multi-member districts that have been its “reserved seats” in election after election, it will likely be the difference between the ruling coalition’s maintaining or losing a majority in the upper house. What losing the majority due to Komeitō’s weakness would mean for its quarter-century-old coalition with the LDP remains to be seen but given that some in the LDP have been vocally opposed to the coalition, those voices could be more insistent, particularly if Prime Minister Ishiba Shigeru were replaced by a more conservative successor.
