In Sunday's House of Representatives election, Japan's Liberal Democratic Party (LDP) faced a rare situation in the proportional representation segment. Despite securing votes for 81 seats, a shortage of candidates led to ceding 14 seats to other parties. Such occurrences are uncommon in past elections.
Sunday's House of Representatives election featured 176 seats in the proportional representation segment. The Liberal Democratic Party (LDP) secured 67 seats, an increase of eight from the previous 2024 general election. However, with votes supporting 81 seats but only 319 candidates fielded—up 34 from before—14 seats were ceded to other parties due to shortages.
Many LDP candidates who ran in both single-seat constituencies and proportional representation won their constituencies, leading to shortfalls in four blocs: Tokyo, Southern Kanto, Hokuriku-Shinetsu, and Chugoku. Under the Public Offices Election Law, the excess seats were transferred: six to the Centrist Reform Alliance (CRA); two each to the Japan Innovation Party, the Democratic Party for the People, and Team Mirai; and one each to Sanseito and Reiwa Shinsengumi.
A senior LDP member expressed mixed feelings, stating, “When the lower house was dissolved, I never imagined we’d win this big.” A similar incident occurred in the 2005 general election over postal privatization, where the LDP won a record 77 proportional seats under the current system but ceded one in the Tokyo bloc to the Social Democratic Party.
Team Mirai, which expanded its lower house presence, ceded two seats in the Kinki bloc—one to the CRA and one to the Japan Innovation Party. This happened because two candidates who ran in both failed to secure 10% of valid votes in their constituencies, disqualifying them from proportional success. The CRA received seven such seats in total, achieving 42 proportional seats overall, fewer than the 64 won by the Constitutional Democratic Party of Japan and Komeito in the prior election. The CRA fielded 28 candidates from Komeito, with top list positions held by Komeito affiliates, ensuring all won seats.
Candidate shortages in proportional representation typically arise from landslide constituency victories, marking this as an unusual outcome.
