TOKYO - The upcoming Liberal Democratic Party leadership election will determine not only who leads Japan’s ruling party but also who is likely to become the country’s next prime minister, and the voting system itself plays a decisive role in shaping the outcome. The election is decided by a combination of votes from LDP lawmakers in the National Diet and ballots cast by the party’s grassroots members across Japan, creating a two-stage process that balances national and local influence.
In the first round of voting, all 296 LDP lawmakers cast a ballot, while party members nationwide, numbering over 900,000, also take part. The results of the grassroots vote are not counted individually but instead converted into 296 “prefectural votes,” giving equal weight to the membership as to the lawmakers. This means the initial round is contested on the basis of 592 votes in total—half from the Diet and half from the rank-and-file membership. If any candidate secures a majority of these votes, the contest is decided immediately.
However, if no candidate reaches an outright majority, a runoff is held between the two top contenders. In this second round, the balance of power shifts. LDP lawmakers again cast 296 votes, but instead of reflecting hundreds of thousands of ballots, Japan’s 47 prefectural party chapters each cast just one vote, regardless of the size of their local membership. That brings the total to 343 votes in the runoff, with the Diet members’ ballots carrying far greater weight than those of the local organizations.
This system has often been criticized as giving lawmakers in Tokyo the final say, particularly in a runoff, but party leaders argue that it preserves a balance between grassroots voices and parliamentary strength. As a result, the dynamics of the election can change dramatically between the first and second rounds, depending on whether party members’ preferences align with the choices of LDP lawmakers.
It is against this backdrop that Agriculture, Forestry and Fisheries Minister Koizumi has added intrigue to the race by traveling abroad just two days before the vote. While grassroots members’ ballots will give him a nationwide presence in the first round, his real challenge lies in securing enough Diet member backing to prevail in a potential runoff where their votes carry far greater weight. Koizumi is in the Philippines attending the ASEAN+3 Agriculture and Forestry Ministers’ Meeting, where he met with the Philippine agriculture minister on October 2nd to press for the lifting of a ban on Japanese grape exports, including Shine Muscats. By emphasizing official duties over campaign appearances, he is signaling responsibility, but he risks losing opportunities to court undecided lawmakers at home.
That may explain why, upon his return, Koizumi moved quickly to meet Chief Advisor Aso on October 3rd, reportedly to seek his support in a possible second-round showdown. With the runoff rules favoring lawmakers’ votes, Aso’s influence over blocs of Diet members could prove decisive. Meanwhile, rival Takaichi is said to be struggling to consolidate backing from lawmakers, and her camp has begun reaching out to supporters of Foreign Minister Hayashi, who is closing the gap. Hayashi’s team believes that an additional 30 Diet member votes would secure him a place in the runoff and is targeting the 50 lawmakers who remain uncommitted. In a contest where the balance of power shifts sharply between the first and second rounds, these maneuvers underscore how crucial the support of Diet members will be in determining not just who advances, but ultimately who becomes prime minister.
