In Japan's recent House of Representatives election held on October 8, the Liberal Democratic Party (LDP) faced challenges in securing proportional representation seats, resulting in the loss of 14 seats to rival parties. The party's inability to fill its candidate list adequately led to this shortfall, with other parties benefiting from the vacancies created by the LDP's insufficient candidate presence. The proportional representation system in Japan allocates seats based on a party's vote count, using the 'D'Hondt method' for seat distribution. As such, the LDP's lack of candidates hindered their potential to gain additional representation in the proportionate block.

In the Tokyo district, where the LDP was expected to perform well, they managed to secure only 8 out of the 19 proportional representation seats available. Most of their candidates (29 out of 32) had declared candidacies in single-member districts simultaneously, and as all of them won their respective local contests, this limited the number of seats they could claim in the proportional representation category. Consequently, only 3 candidates were able to win a seat from the proportional representation list, leading to 5 candidates failing to secure a seat.

Similar outcomes occurred in other regions, including the South Kanto area, where the LDP lost 6 seats, and the Hokuriku-Shinetsu region, losing 2 seats, while also giving up another seat in the Chugoku area. These results suggest a growing trend of the LDP facing challenges related to candidate management and the implications of their electoral strategies, potentially signaling a shift in voter preferences and the need for improve their organizational structure for future elections.
