Incumbent LDP President and Prime Minister Shigeru Ishiba announced on 7 September that he would resign as party president and prime minister, amid infighting within the LDP and pressure for a snap election. Ishiba's resignation also came amid the LDP's poor performance in the 2024 general election and the 2025 House of Councillors election, which resulted in the party losing its majority in both chambers.[4][5]
In this election, all five candidates that ran for the LDP leadership previously ran unsuccessful campaigns in the past. Running in the election were: former Minister of State for Economic Security Sanae Takaichi, Agricultural Minister Shinjirō Koizumi, Chief Cabinet Secretary Yoshimasa Hayashi, former Economic Minister Takayuki Kobayashi and former Foreign Minister Toshimitsu Motegi.
In the first round of voting, Takaichi came in first place during the first round of voting with 31.07% of the vote.[6] Koizumi came in second with 27.84% of the vote, meaning that both Koizumi and Takaichi advanced to the runoff.[6] In the runoff, Takaichi garnered 54.25% of the vote against Koizumi, resulting in the election of the LDP's first woman president. If confirmed during the Diet's extraordinary session on 15 October, Takaichi will become the first woman to serve as Prime Minister.[7][8]
Election procedure
The election process for the President of the LDP is established in the "Rules for the Election of President of the Party". In order to officially qualify as a candidate in the election, a candidate must be an LDP member of the National Diet and must receive a nomination from at least 20 fellow LDP Diet members.
The LDP selects its leader via a two-round election involving both LDP members of the Diet and dues-paying party members from across Japan. In the first round, all 295 LDP members of the Diet will cast one vote while party member votes (915,574) are translated proportionally into votes equaling the other half of the total ballots (also 295) to equal 590 total first round votes. If any candidate wins a majority (over 50%, ~296 votes) of votes in the first round, that candidate is elected president. If no candidate reaches that threshold, than an instant runoff will be triggered; in this second round, the two candidates who received the highest vote share will advance, and the winner will be decided by the 295 Diet members, and the party's 47 prefectural chapters, with each chapter being allotted one vote each, equally a total 342. The winner of the second round will become the next party president.[9]
According to NHK News, there are two ways to conduct a presidential election, depending on whether or not it includes a party member vote. Party rules stipulate that the election will be contested through a combination of votes from Diet members and "party member votes" from party members across Japan; this was how the previous presidential election was conducted, with over 1.05 million party members voting nationwide. However, during "particularly urgent cases," such as the president's resignation during his term, Diet members and 3 representatives from each of the 47 prefectural party chapters will vote at a general meeting of both houses of parliament, which replaces the party convention; the last time this occurred was in 2020, when Yoshihide Suga replaced Shinzo Abe as party president.[10]TBS News reported on 8 September that the presidential election would likely be conducted in the former format, allowing local party members to vote.[11] This was confirmed the following day.[12][13][14] 915,574 citizens are eligible to vote; their votes will be proportionally weighted.
As with the last leadership election, the LDP Presidential Election Commission is chaired by Ichiro Aisawa.[15] The party's public relations headquarters published the official slogan of the election on 19 September: "#ChangeTheLDP".[16]
Background
Premiership of Shigeru Ishiba and impact of election losses
Shigeru Ishiba was elected party president and prime minister in 2024; he led the party through two subsequent elections, in which the LDP lost its majority in both the House of Representatives and House of Councilors, respectively.
Elections for Japan's Upper House, the House of Councilors, were due in July 2025. Once again, the LDP–Komeito coalition lost its majority, as parties like the CDP and DPFP, as well as the far-right nationalist Sanseitō party, made gains.[24] After both elections, Ishiba invoked a parliamentary plurality in both houses, and believed the LDP had a responsibility to lead the government, as it would in most other parliamentary democracies.[25] Pressure continued to mount on Ishiba to resign as LDP President, but he refused and said he planned to continue serving as Prime Minister.[26] It was falsely reported on 23 July 2025 that Ishiba would resign in late August, before Ishiba himself debunked the rumors at LDP headquarters that same day.[27][28][29] Mid-career and junior members of the LDP, primarily members and former members of the Motegi faction, began collecting signatures to call for the early convening of a joint meeting of the party representing both houses of parliament.[30]
The consecutive election losses impacted the composition of party factions, most of which had officially disbanded after 2024, but still played a crucial role in the LDP's internal politics. 'The Nikkei reported shortly after the Upper House elections that the strength of the Abe faction (a more conservative party faction once led by the late former Prime Minister Shinzo Abe) has been reduced by almost 40% since October 2024.[31]
Potential candidates emerge
Shinjiro Koizumi was appointed to the cabinet by Shigeru Ishiba in May 2025.
Even before Ishiba announced his resignation, several senior LDP members were floated by the media as possible successors to him as party president, with some members even hinting at the possibility of running. On 18 July 2025, before the Upper House election was even held, Sanae Takaichi said she had “already made up her mind” about running and expressed desire to become LDP President.[32] The day after the election, she met with some of her supporters, as well as former Prime Minister and party elder Tarō Asō.[33]Takayuki Kobayashi, a fellow staunch conservative and candidate in the previous leadership election, also met with supporters.[34] Kobayashi met with them again in August.[35]
Shinjiro Koizumi, a son of former Prime Minister Junichiro Koizumi and former cabinet minister under Shinzo Abe, was appointed as Agriculture Minister by Ishiba in May 2025.[36] Later in August, after the Upper House elections, he met with former Prime Minister Fumio Kishida; Koizumi came in third place in the previous presidential race with support from some of Kishida's faction members.[37] Koizumi later met with Tarō Aso that same month.[38] When he was asked if he was considering running earlier in July, Koizumi avoided the question, instead claiming he would primarily focus on rice policy.[39]
Chief Cabinet Secretary Yoshimasa Hayashi, a veteran conservative who had served under numerous Prime Ministers, stated his intention to continue supporting Ishiba on 22 July, the day of the Upper House election.[40]
Due to the government's minority status, Nikkei Asia reported that the next party leader would have to have good connections with the opposition.[41]Sankei Shimbun reported that the expectation was that the next leadership election would be between Koizumi and Takaichi.[42]
Pressure builds, emergency election considered
On 6 August, Ishiba ordered an investigation into political party branches over corporate donations, which prompted criticism from within the party.[43] During a joint plenary session on 8 August, the LDP decided that it would determine whether or not to move forward with an "emergency presidential election” based on opinions by lawmakers and prefectural branch chiefs. During the meeting, Ishiba repeated his intention to stay in office.[44] A majority of lawmakers and prefectural branch chiefs (172 at the time) was required to demand a presidential election.[45]
A joint meeting of both houses of parliament was held on 8 August, with 253 members in attendance and 35 speaking. At the meeting, it was decided that the LDP Presidential Election Management Committee would consider whether to hold an early presidential election in accordance with Article 6, Paragraph 4 of the LDP rules.[46][47]
Later on 13 August, Ishiba repeated his intention to continue in office as the LDP began to consider holding an emergency presidential election to force Ishiba to face the party in another leadership vote.[48] The LDP's presidential election management committee began to discuss on the procedures for deciding whether or not to hold a special presidential election on 19 August.[49] The committee announced the following day that they would begin the process once the party's internal review of the Upper House election was completed.[50]Kyodo News reported that the committee would explore the idea of disclosing the names of lawmakers who sign a paper demanding that a special election take place.[51] This was confirmed on 27 August with the deadline to confirm lawmakers intentions being announced as 8 September.[52] NHK reported on 28 August that the party would solidify its decision in September. Deliberations continued within the party as the LDP's General Review Committee compiled its review of the election results.[53]
The LDP Presidential Election Management Committee met on 19 August, and it was decided to proceed with consideration of the method of confirmation, which would involve having Diet members who wish to hold an early presidential election submit their request in writing.[54][55] Regarding the advancement of the presidential election, while there are forces defending Ishiba, there is also a growing opinion that Ishiba should be held accountable and that an emergency presidential election should be held instead, coming from non-mainstream factions such as the former Abe, Motegi, and Nikai factions, as well as young and mid-career Diet members and some prefectural federations.[56] Even among the three political officials (Vice Ministers and Parliamentary Vice-Ministers) in the Ishiba Cabinet, Kobayashi Fumiaki, Saito Hiroaki, and Kanda Junichi, there are calls for an emergency presidential election, and some have even expressed a willingness to resign from their positions if necessary.[57][58][59]
On 31 August, the protests calling for the resignation of the Ishiba administration was held in front of the Prime Minister's Office, with 4,000 people (according to the organizers) attending. However, compared to the "Ishiba Resign Demonstration" held on the 25th of the previous month, which was attended by 1,200 people (according to the organizers) in support of the continued existence of the Ishiba administration, it received almost no coverage, and Senator Masashi Nishida questioned the media's reporting stance.[60]
LDP Special Advisor Taro Aso announced his support for an emergency presidential election on 3 September 2025. Animosity had developed between Ishiba and Aso since the previous leadership election.
Support for Ishiba within his cabinet was mixed. Digital Minister Masaaki Taira stated he would "naturally support" Ishiba if he were to stand for re-election in a hypothetical emergency election.[61] Economic Revitalization Minister Ryosei Akazawa, who had spearheaded negotiations regarding tariffs with the Trump Administration in the United States, said he would also support Ishiba. Akazawa, also hailing from Ishiba's own Tottori Prefecture, said he took immense pride in his role as Ishiba's aide.[62] Ishiba's Defense Minister, Gen Nakatani stated bluntly that "The LDP should not hold a special presidential election" on 26 August.[63] Foreign Minister Takeshi Iwaya stated that an emergency election would have a “negative impact” on Japanese foreign policy, as it would disrupt continuity.[64] Cracks started to form in late August, as junior cabinet ministers began to speak out in favor of an emergency election. Parliamentary Vice Minister of Justice Junichi Kanda[ja] said on 27 August that he was considering resigning from the Cabinet to advocate for a special election.[65] In a statement on Twitter the following day, State Minister (Deputy Minister) of the Environment Fumiaki Kobayashi said that a special presidential election should be held as soon as possible, claiming he would resign as a vice minister if necessary.[66] The day afterwards, several members of the Mortegi faction, including Deputy Minister of Agriculture, Forestry and Fisheries Hiroyoshi Sasagawa, agreed to support an early leadership election.[67] That same day, former Economic Minister Takayuki Kobayashi, himself a candidate in the previous leadership candidate, said he would sign documentation requesting an emergency election.[68] On 31 August, Deputy Finance Minister Hiroaki Saito announced his support for a special election.[69] This was followed almost immediately by similar calls from Parliamentary Vice Minister of Land, Infrastructure, Transport and Tourism Yasuhiro Takami, former Education Minister Masahiko Shibayama, and House of Councilors Member Hiroshi Yamada.[70] As more party lawmakers began to speak out, focus began to shift towards prefectural party chapters; some MPs said they would make a decision based on the wishes of their local community. By 4 September, the party chapters in the prefectures of Hokkaido, Hyogo, Kagawa, Ehime, and Miyazaki all called for a special election. Fukushima, Okayama, and Oita prefectures, opted not to call for an election. Party chapters in Ibaraki, Yamagata, Ibaraki, Saitama, Niigata, Yamanashi, and Nagano prefectures "consolidated opinions” in favor of an election, while 33 prefectural federations continued to debate their own respective responses.[71] The previous day, LDP Special Advisor, former Prime Minister, and power-broker Taro Aso, declared his support for an early leadership election. Aso had been calling for Ishiba to step down since the Upper House election in July, and had feelings of animosity towards Ishiba since he won the party leadership in September 2024.[72] Agriculture Minister Shinjirō Koizumi meanwhile defended junior ministers calling for a special election, saying, "It would be strange for them not to feel a sense of crisis after losing [a majority in] both the House of Representatives and House of Councillors…” He continued to call for party unity, and said he would make up his mind after the review of the results was completed.[73] In late August, former Defense Minister Tomomi Inada stated she understood public opinion questioning why lawmakers implicated in the slush fund scandal "who have not taken responsibility themselves" were pressuring Ishiba to step down.[74] As August came to close, it was becoming clear that while the LDP's party approval had fallen, Ishiba Cabinet approval had increased.[75][76]
Three senior party executives, Policy Research Council Chairman Itsunori Onodera, LDP General Affairs Chairman Shun'ichi Suzuki, and Secretary-General Hiroshi Moriyama, all announced their resignations on 2 September 2025.
At a "Joint Party Meeting of Members of both Houses of Parliament" held on 2 September, the LDP published its summary of Upper House election results, stating that its measures to combat rising prices did not resonate with the public and that it lost trust due to issues related to politics and money. Ishiba once again apologized for the loss of a majority, and clarified "I am not at all clinging to my position, but rather it is my responsibility to make proper decisions at the appropriate time." He subsequently told reporters that he intended to stay in office. That same day, three senior party executives resigned their positions seemingly simultaneously. LDP Policy Research Council Chairman Itsunori Onodera, LDP General Affairs Chairman Shun'ichi Suzuki, and LDP Secretary-General Hiroshi Moriyama all conveyed their intentions to resign to Ishiba.[77] After this, Ishiba reiterated once again that he intended to remain as Prime Minister.[78] As this was happening, some members of Ishiba's cabinet continued to reiterate their support. Foreign Minister Takeshi Iwaya said that there was “no need” and “no time” for an emergency leadership election, and that "There is no one better suited to the job than Prime Minister Ishiba." Discontent continued to brew however, former Economic Minister and previous leadership candidate Sanae Takaichi called for a special election.[79] Koizumi continued to give unclear answers, simply stating that "it is not good at all for the public to continue to see the image of a party in a state of disarray.” and that he would “face this issue head on." [80] In a survey, NHK reported that ~100 lawmakers supported an election, 50 oppose, ~100 were undecided, around 30 refused to comment, and ~10 were unreachable.[81] Pressure only continued to mount as Deputy Minister of Justice Masahiro Kōmura announced on Facebook on 3 September that he would support an early presidential election, followed by Deputy Minister of Education Arata Takebe and Deputy Minister of Digital Affairs Yasushi Hosaka.[82] On 4 September, Koizumi stressed that “we don't have time to waste on political battles” and once said he felt a sense of crisis.[83] That same day, party chapters from Oita and Okayama decided not to call for an early election.[84] Ishiba continued to repeat that he planned to remain Prime Minister.[85] In early September, Chief Cabinet Secretary Yoshimasa Hayashi met with about 10 LDP lawmakers close to him.[86] LDP Chief Advisor Aso and former Secretary-General Toshimitsu Motegi met the same month.[87]
On the evening of 5 September, Ishiba met with close allies within his cabinet, including Foreign Minister Iwatake and Minister of Internal Affairs and Communications Seiichiro Murakami, at a hotel in Tokyo.[88] Earlier that day, Minister of Justice Keisuke Suzuki became the first cabinet minister to support an early presidential election, writing that "to restore trust in the party, it is necessary for the party to unite and start anew from scratch."[89] That same day, a Kyodo survey of the LDP's 295 lawmakers found that over 120 lawmakers supported an emergency presidential election, while just under 50 opposed it.[90] By this point, Ishiba had reportedly threatened to ask the Emperor to dissolve the House of Representatives and call a general election, which would require invoking Article 7 of the Constitution.[91] On the following night, on 6 September, both Koizumi and former Prime Minister Yoshihide Suga (who had served as Vice President of the Liberal Democratic Party under Ishiba) reportedly urged Ishiba to resign at the Prime Minister's Official Residence in Tokyo.[92][93][94]
Ishiba resigns
"Now that negotiations on U.S. tariff measures have reached a conclusion, I believe this is the appropriate time to step aside and make way for the next generation."
The Press Conference in which Ishiba resigned as PM
On 7 September, Shigeru Ishiba announced that he would resign as President of the Liberal Democratic Party of Japan.[4][96][97]The Japan Times reported that pressure from Suga, and Koizumi in particular, was key in Ishiba's decision, as the latter "urged" him to quit after staying at the official residence for about 2 hours (Suga had only stayed for 30 minutes).[98][99]
At a press conference at the Prime Minister's Office, Ishiba stated he sought to claim "responsibility" as party leader for losses in recent elections, and to avoid dividing the party.[5] Ishiba's announcement effectively cancelled the emergency election process entirely. He instead instructed Moriyama, whose resignation had not been accepted by Ishiba, to begin the process to hold an extraordinary presidential election.[100] Ishiba said he determined now was the "appropriate time" to step aside, after a written version of the Japan–U.S. tariff agreement had been finalized.[101] In his exit speech, Ishiba touted various accomplishments; 67 out of 68 bills submitted by the government had been passed by the Diet (in part thanks to opposition parties).[102] Ishiba said strides were made in improving the work conditions of JSDF personnel. He also said he felt confident in his foreign policy, citing successful meetings with US President Donald Trump, South Korean President Lee Jae Myung, and Indian Prime Minister Narendra Modi.[103] Ishiba said he was "filled with deep regret" that he was unable to meet the expectations of the Japanese people.[104] Ishiba stated he felt his biggest regret in particular was failing to address public distrust in politics, citing the continuing impact of the slush funds scandal. Ishiba said he was concerned that the LDP was losing the public's trust, which could lead to Japan falling into populism. He urged the party to "restart from scratch" in order to change the public perception that the party had not changed at all.[105]
Ishiba promised to continue serving as Prime Minister until a new leader was elected, and did not endorse a candidate in the subsequent election. His tenure lasted about one year.[95]
Campaign
Race begins to take shape
Shortly after the resignation announcement of Shigeru Ishiba, polling and media reports found former presidential candidates Sanae Takaichi and Shinjiro Koizumi as the frontrunners of the election[106][107]
Sanae Takaichi, Shinjiro Koizumi, and Yoshimasa Hayashi were seen as potential candidates by Nikkei Asia upon Ishiba's resignation, with Takaichi and Koizumi being called early frontrunners.[106] All three had run in the previous presidential election, and while Takaichi had served as Economic Security Minister under Fumio Kishida, Koizumi and Hayashi were serving members of the cabinet, as Agriculture Minister and Chief Cabinet Secretary, respectively.[108] Among the general public, opinion polls showed Koizumi and Takaichi were deadlocked at 19.3% each.[107]President magazine predicted that a dark-horse candidate, beyond Koizumi and Takaichi, could emerge in the race to rebuild the party from scratch.[109]
On 8 September, the race began to take shape.[110] Ishiba clarified that he had “no problems” with cabinet ministers seeking the presidency, and would not attempt to block anyone from doing so.[111] Ishiba later implied he thought Koizumi, with whom he held similar policy beliefs, was a suitable successor.[112] The day following the resignation announcement, Takayuki Kobayashi told reporters he would discuss possibly running in the election with colleagues, before making a decision, but hinted at party unity being a theme of his potential campaign.[113][114] The same day, Toshimitsu Motegi announced to reporters that he would be running in the leadership election. The former party Secretary-General became the first to throw his hat in the ring.[115] He said he was “convinced” he would be able to gather the 20 signatures necessary to officially run. Later that morning, it was reported that Hayashi planned to announce his campaign. He said he wanted to consult with some of his colleagues before making the decision.[116] The party's Yamaguchi Prefecture branch reportedly urged Hayashi to run.[117] After conveying his intention to former Prime Minister Fumio Kishida, who supported Hayashi in his last leadership bid, Hayashi solidified his intentions to run.[118][119][120] The Sankei Shimbun reported the same day that Takaichi was preparing a campaign of her own, and was beginning to gather endorsements from party members.[121]
As the LDP was leading a minority government in the lower house, the party president's relationship with opposition parties, including potential coalition partners, was a factor in the election.[122][123] The Komeito, a coalition partner of the LDP since Shinzo Abe began his second premiership in 2012, warned the LDP against deviating from "conservative centrism”.[124] According to the Yomiuri Shimbun, Hayashi and Koizumi had maintained good relations with Ishin no Kai, which had been flirting with the idea a coalition with the LDP since the Upper House elections.[125][126] Koizumi met with Ishin leader Hirofumi Yoshimura in August while Hayashi met with former Ishin leader Nobuyuki Baba on 8 September.[127][128] Motegi was said to have good relations with the Democratic Party For the People (DPFP), while Takaichi had ideological similarities with Sanseitō.[126]Sankei claimed that senior members of Komeito's leadership threatened to leave the coalition with the LDP if Takaichi succeeded Ishiba.[129] As with the past election, party bosses influenced the election. In early September, former Prime Minister Fumio Kishida, urged the party to use the leadership selection as an opportunity to position it a moderate center-right conservative party.[130] Later that month, it was reported that former Prime Minister Tarō Asō was considering Koizumi as his top choice.[131]
On 10 September, Motegi held a press conference, during which he said he would seek to expand the current government coalition in order to achieve government stability. Not unlike Koizumi, Motegi stated his opposition to banning corporations from making donations, and also said he would try to reduce the number of foreign workers in Japan over time.[132] That same day, it was reported Kobayashi had finalized his plans to run.[133] Kobayashi held a press conference the next day announcing that he would run for the party presidency in his second leadership bid.[134] After a meeting with the DPFP's Kazuya Shimba, Koizumi reportedly laughed when he was asked by the former if he would run.[135] The following day, Representative Hitoshi Kikawada told NHK that Takaichi would run.[136] Motegi's campaign meanwhile announced support for tax cuts to stimulate economic growth.[137] As momentum from his home Kanagawa Prefecture grew for Koizumi to run, he said he would make a final decision after meeting with local supporters.[138] By 12 September, Hayashi's poll numbers had begun to rise as Takaichi and Koizumi continued to compete for first place among said polls.[139] The next day, Koizumi met with supporters, informing them he would stand in the election.[140]
The Big Three: Hayashi, Takaichi, Koizumi
Finance Minister Katsunobu Katō, a staunch conservative who ran in the previous election, was announced as Koizumi's campaign manager.
On 16 September, Hayashi held a press conference affirming his intent to run in the presidential election, planning to release a full manifesto at the campaign launch held a few days later.[141][142] Hayashi pledged to continue the work started by the Kishida and Ishiba administrations, running as a continuity of candidate while embracing some policies of his own.[143] Some of his initial policies included amending the Constitution and increasing wages to counter the effects of inflation. [144] Hayashi, who had 30 years of experience when he entered the race, expressed regret over Ishiba’s resignation, but said he was open to expanding the government coalition to include more parties.[145] Hayashi was endorsed by Defense Minister Gen Nakatani not long after the press conference ended.[146] Shortly after Hayashi's brief press conference, Kobayashi held one of his own, which served as his official campaign announcement.[147] Kobayashi had reportedly been urged by Kōichi Hagiuda, an ally of the late Shinzo Abe, to support Takaichi instead of running his own campaign.[148] Running on the image of “generational change” Kobayashi said he “felt a strong sense of crisis" and would seek to rebuild the party after the successive election losses, and would focus on working with opposition parties; Motegi meanwhile had continued to advocate for expanding the coalition.[149] Promising to return Japan to its status as "technological superpower”, Kobayashi said he would introduce tax cuts and raise defense spending beyond 2% of GDP.[150] He also expressed concern about misinformation spreading on social media, and said he would work to stop foreign powers such as China from interfering in Japanese society and democracy.[151] Presenting himself as a bridge between conservative policies and the younger generations, Kobayashi announced Yasukazu Hamada, a former Defense Minister, as his campaign manager.[152] Later that same day, Shinjiro Koizumi confirmed, during a press conference in his capacity as Agriculture Minister, that he also intended to run in the election.[153] Before official campaigning began, Koizumi attempted to moderate his reformist image by appealing to conservatives within the party.[154] On 15 September, Finance Minister and staunch conservative Katsunobu Katō opted against running in the election and endorsed Koizumi.[155] Katō, who had ran in the previous presidential election, was announced as Koizumi’s campaign manager; Kato had repotredly been approached by Takaichi’s campaign but ultimately declined to endorse her.[156] Koizumi stressed the importance of party unity, and said he would shelf several policies he had previously advocated, such as legislation for selective surnames for married couples.[157]Nikkei reported this was becoming a common theme in the election, with most candidates avoiding major policy proposals that could further divide the party.[158]
On 18 September, Hayashi held his campaign announcement press conference, during which he revealed the policies of his “Hayashi Plan”, which would aim to "create a future for Japan in which everyone can have dreams, hopes, and pride."[159] Vowing to make full use of is experience, Hayashi said he would pursue internal reforms to rebuild the image of the LDP, as well as realize 1% wage increases and legislation to ensure social security would be sustainable by the 2040s, which would he said would help create a more resilient economy.[160] While generally socially moderate on social issues, the Hayashi Plan included proposals to reintroduce the system of multiple-seat constituencies, as a way to potentially address competition in single-member districts, which had been in use since the 1996 general election.[161][162] Hayashi said the party should unit under a “conservative” platform, in what The Japan Times said was an appeal to party members who preferred a moderate conservative vision as opposed to a more more right-leaning one. Hayashi became the third candidate to officially enter the race, after Motegi and Kobayashi.[163] The same day as Hayashi’s announcement, Sanae Takaichi confirmed her own campaign.[164] While not elaborating on policies, Takaichi was believed to be a proponent of government stimulus, having been described as a “fiscal dove”.[165] Meanwhile, it was reported that Koizumi had sought advise from former Prime Minister Fumio Kishida; Seiji Kihara, another conservative, joined his campaign.[166] By then, Koizumi was leading most opinion polls, followed by Takaichi, as Hayashi and Motegi were mostly tied for third place.[167] Earlier that day, Hayashi met with the DPFP's Kazuya Shimba, as Koizumi met with LDP party elder Tarō Asō.[168] Hours later, former Digital Minister Taro Kono and former Birthrate Minister Seiko Noda, both candidates in previous presidential elections, announced their intentions not to run, with both endorsing Koizumi for president.[169][170]
Cabinet ministers Yoshimasa Hayashi (left) and Shinjirō Koizumi (right) both announced their campaigns the week of 15 September. While Hayashi campaigned as a continuity candidate, Koizumi softened his reformist image to broaden his appeal.
With the influence of the far-right diminished after the party’s election losses, Takaichi attempted to moderate her image to appeal to a broader voter base; when she was asked about setting a clear defense spending target or visiting the controversial Yasukuni Shrine, Takaichi avoided giving a clear answer, and also expressed willingness to work with opposition parties.[171] To help increase take-home pay, Takaichi said she would pursue a policy of "cash handouts + tax deductions" while also declaring her support for raising the income tax threshold and removing taxes on gasoline, policies supported by several opposition parties.[172] At her press conference held on 19 September, Takaichi stated "We must once again proclaim, 'Japan is back.' I stand here with a lofty ambition and a burning desire to 'take Japan to the top of the world once again.' We must strengthen Japan's national strength."[173] Takaichi had to apologize twice after the host of her campaign launch, LDP MP Hitoshi Kikawada, singled out reporters by skin color.[174] Kikawada, who served as the moderator for the press conference, called on reporters using the phrases, "someone with darker skin" and "someone with lighter skin."[175] The fourth candidate to enter the race, this was Takaichi’s third leadership election.[176]
On 20 September, Koizumi officially announced his campaign.[177][178] In his press conference, Koizumi stated, "I am determined to take the lead in rebuilding the LDP into a party that realizes the peace of mind and safety desired by the people."[179] Promising to abolish the gasoline tax and have a budget ready by the fall. Like other candidates, Koizumi said he was open to expanding the coalition government.[180] Koizumi said he would “rebuild” the LDP after ‘failing to address the public's concerns and lacked the imagination to support those suffering from rising prices.’[181] Koizumi’s policy platform included increasing foreign investment, increasing wages by ¥1 million over five years, income tax reform, improvement of working conditions, ensuring the 2% of GDP on defense goal will be met, regional revitalization, and internal party reform.[182][183] On the issue of selective surnames, Koizumi calcified that while his personal opinion remained unchanged, he believed party unity took precedent.[184]Sankei reported that shelving these and other policies had the potential to hurt Koizumi’s reformist image.[185] On the same day, former Foreign Minister Yōko Kamikawa, a candidate in the previous election, announced that she would not run.[186] With Koizumi’s entry into the race, he was the fifth and final candidate, setting the stage for a 12-day official campaign period beginning on 22 September.[187]
Campaigning begins
Takaichi's polling numbers briefly benefited following the first two debates
As the official campaign period began, Koizumi and Takaichi were among the frontrunners based on opinion polling. Shortly before the campaign period began, Takaichi led in polls amongst party members while Koizumi led polls among party supporters.[188] Takaichi benefited from a great number of supporters among the Seiwa Seisaku Kenkyūkai, Shikōkai and Shisuikai factions.[190] Koizumi benefited most from the Heisei Kenkyūkai faction and those who did not identify with a faction.[190] Hayashi received the most support from the Kōchikai faction and those who did not identify with a faction.[190] Kobayashi received the most support from factionless LDP members while Motegi was overwhelmingly supported by the Heisei Kenkyūkai faction.[190]
On 23 September and 24 September, debates were hosted by the Liberal Democratic Party and the Japan National Press Club respectively.[191] After the debates, Takaichi took the lead amongst party supporters with Koizumi's support dropping.[189] That same poll showed Yoshimasa Hayashi gaining traction, increasing his support in third place.[189] On 26 September, street speeches were organized by the five candidates in Aichi.[191] That same day, Koizumi issued an apology after admitting that a member of his election campaign team had asked supporters to post favorable comments about him, and comments attacking other candidates online.[192][193] He also apologized for the agricultural ministry's handling of a licensing deal for a "prized grape variety" that sparked an official protest from producers.[194] On 28 September, a poll showed Koizumi with a narrow lead over Takaichi among LDP members while also holding a substantial lead over her among LDP supporters.[195]Bloomberg News noted that the LDP was split between Koizumi and Takaichi as to who was better to lead the party.[196]
A policy debate hosted by the LDP was held between all five candidates on 30 September.[191] That same day, Takaichi expressed her openness for policy talks amongst the country's right-wing parties such as with the Conservative Party and Sanseitō.[197]The Japan Times noted after the LDP debate that Koizumi was "toning down" his reformist agenda having previously campaigned as a reformist candidate within the LDP.[198] On 2 October, street speeches were organized in Osaka.[191]
Election results
On 3 October, the day of the deadline for LDP members to vote arrived.[191] The following day, the counting of votes for members of parliament and party members at party headquarters began.[191]Sanae Takaichi came in first place during the first round of voting with 183 (31.07%) of the vote.[6]Shinjirō Koizumi came in second with 164 (27.84%) of the vote, meaning that both Koizumi and Takaichi advanced to the run-off to elect the party leader.[6] This meant that Japan was poised to either elected the country's first female prime minister in Takaichi or the country's youngest prime minister in modern Japan history in Koizumi.[199]Yoshimasa Hayashi came in third place with 134 (22.75%) of the vote, nearly becoming competitive for second place alongside Koizumi, but was ultimately eliminated from the election.[6]Takayuki Kobayashi and Toshimitsu Motegi came in fourth and fifth place respectively garnering 59 (10.02%) and 49 (8.32%) of the vote.[6]
In the runoff, Takaichi garnered 185 votes (54.25%) of the vote against Koizumi's 156 votes (45.75%), resulting in the election of the LDP's first woman president and most likely Japan's first woman Prime Minister.[7]
