The Controversy Unfolds in Japan's Political Arena
In a tense exchange during a House of Councillors budget committee session on May 11, 2026, Prime Minister Sanae Takaichi categorically rejected allegations that members of her political camp orchestrated an online smear campaign targeting rivals. The claims, first detailed in a late April edition of the influential weekly magazine Shukan Bunshun, suggested that her publicly funded first secretary and other staff produced and disseminated hundreds of defamatory videos across social media platforms. These videos purportedly attacked fellow Liberal Democratic Party (LDP) leadership contenders and opposition figures, raising serious questions about the ethics of digital campaigning in Japan's evolving political landscape.
Takaichi, Japan's first female prime minister since taking office in October 2025, has built much of her public image on savvy social media engagement. Her denial came amid growing scrutiny over the role of anonymous online accounts in shaping public opinion, especially following the LDP's resounding victory in the February 8, 2026, Lower House election. This snap poll delivered the party a postwar record supermajority of 316 seats out of 465, crediting Takaichi's personal popularity and digital outreach strategy.
The prime minister's firm stance—"I have been told that my office and campaign team did not in any way disseminate negative information about other candidates or create and distribute such videos"—underscored her trust in her staff. She went further, questioning the credibility of the reporting by stating, "Do I believe a weekly magazine or do I believe my secretary? I believe my secretary." This marked her second public rebuttal in parliament, the first occurring on May 8.
Sanae Takaichi's Meteoric Rise to Power
Sanae Takaichi's journey to the premiership is a testament to her enduring appeal within conservative circles. Born in 1961 in Nara Prefecture, she entered politics as an independent in the 1993 general election before joining the LDP in 1996. Over three decades, she held key ministerial posts, including Minister for Internal Affairs and Communications under Shinzo Abe and Minister of State for Economic Security under Fumio Kishida.
Known for her hawkish views on national defense, regular visits to Yasukuni Shrine, and advocacy for constitutional revision to establish a "National Army," Takaichi positioned herself as a protégé of the late Abe. Her 2025 LDP presidential bid succeeded where previous attempts in 2021 and 2024 had faltered. On October 4, 2025, she defeated Shinjiro Koizumi in the runoff, becoming LDP president and, days later on October 21, prime minister after securing Diet confirmation.
Takaichi's administration quickly pivoted to economic stimulus—a ¥13.9 trillion package to combat inflation—and defense hikes aiming for 2% of GDP spending by 2026. Her high approval ratings, hovering between 65% and 83%, particularly among younger voters, prompted the February snap election. The LDP's landslide not only solidified her mandate but highlighted her mastery of platforms like X (formerly Twitter) and YouTube, where she overwhelmed rivals in engagement metrics.
Shukan Bunshun's Explosive Revelations
The spark for the current uproar was Shukan Bunshun's investigative report, which alleged a sophisticated "SNS team" within Takaichi's camp churned out 100 to 200 AI-generated short-form videos daily. Led by chief public secretary Koichi Kinoshita, the operation reportedly enlisted AI specialist Ken Matsui from mid-2025 LDP presidential race onward. A current minister's aide was also implicated in the "negative campaign video operation."
Posts were funneled through anonymous accounts such as "True Politics" on TikTok, YouTube Shorts, and Instagram Reels to mask origins. The magazine published message logs, emails from Kinoshita, and links to sample videos as evidence, framing the effort as a deliberate strategy to boost Takaichi while undermining competitors.
This occurred during two pivotal contests: the 2025 LDP leadership race, where Takaichi clinched victory, and the 2026 Lower House election, where the LDP dominated. The report painted a picture of industrialized negativity, leveraging artificial intelligence for scale and anonymity.
Targets of the Alleged Smears: High-Profile Rivals
Specific videos singled out prominent figures. Defense Minister Shinjiro Koizumi, Takaichi's 2025 runoff opponent, faced clips branding him "incompetent" and a "puppet of hereditary politics." Former Foreign Minister Yoshimasa Hayashi was mocked as an "emergency responder" in derogatory skits. Opposition heavyweights like ex-Constitutional Democratic Party leader Yukio Edano were dubbed "professional complainers," coinciding with his failed Centrist Reform Alliance bid where he lost his seat.
Other targets included Democratic Party for the People leader Katsuya Okada. Meanwhile, parallel content lionized Takaichi as a "goddess" figure. Bunshun claimed these efforts amplified during peak campaign phases, with videos reposted across platforms for maximum reach.
- Shinjiro Koizumi: Portrayed as unqualified heir to political dynasty.
- Yoshimasa Hayashi: Ridiculed for perceived ineffectiveness.
- Yukio Edano: Labeled chronic critic without solutions.
- Katsuya Okada: Similar opposition takedowns.
Such personalization exemplifies how digital tools can weaponize personal narratives, blurring lines between fair critique and defamation.
Takaichi's Steadfast Defense and Media Critique
In parliamentary responses, Takaichi emphasized direct confirmation from her team: no videos created or shared. She distanced herself personally, noting personal attacks "are not her approach." Her retort to opposition lawmaker Yuko Mori highlighted media skepticism, accusing Shukan Bunshun of fabricating quotes in brackets—words she claims she never uttered.
This defense aligns with Takaichi's proactive media style, where she prioritizes direct voter communication over traditional press. Since assuming office, she has conducted fewer formal briefings than predecessors but amassed massive online followings. During the 2026 campaign, her YouTube videos alone garnered 450 million views out of 2.8 billion total election-related clips—a tenfold surge from 2024.
As reported by Kyodo News, about half of top Takaichi videos were positive, contrasting with 80% negative coverage of rivals like the Centrist Reform Alliance.
Opposition Pushback and Public Discourse
Opposition figures, including Mori of the Constitutional Democratic Party, pressed Takaichi on accountability, questioning public funding for alleged smear operations. While no formal investigations have launched, the episode has reignited debates on campaign finance and digital ethics.
Public reaction splits along ideological lines: supporters view it as typical political mudslinging exaggerated by media; critics decry it as undermining democratic discourse. Polls post-denial show minimal dip in Takaichi's approval, buoyed by economic deliverables and foreign policy assertiveness.
Social Media's Transformative Role in Japanese Elections
Japan's electoral landscape has shifted dramatically with digital platforms. The 2026 Lower House race saw social media views explode to 2.8 billion, driven by short videos. Takaichi's 65 campaign posts averaged 5,200 reposts each, dwarfing rivals and correlating with LDP's youth surge—92.4% young voter support despite media critiques.
Third-party content dominated (80%), often clipping TV for virality. LDP videos topped party tallies at 230 million views. Yet, this boom amplifies risks: AI deepfakes, fake news, and anonymous smears proliferated, prompting government calls for platforms to remove falsehoods swiftly.
| Platform | Total Views (2026 Election) | Takaichi Share |
|---|---|---|
| YouTube Shorts | 1.2B | 200M |
| TikTok | 900M | 150M |
| Instagram Reels | 700M | 100M |
Data illustrates her dominance, but also vulnerability to countersmears—like Chinese-linked "Traitor Takaichi" campaigns using 3,000 fake accounts during her tenure.
Precedents of Online Smears in LDP Contests
This isn't isolated. In 2025 LDP race, Koizumi's camp faced "fake posts" flooding sites. Broader trends include Russian bots blamed post-2024 LDP setbacks and rising AI disinformation. Government pushes for stricter election interference rules, targeting foreign meddling via social media.
- 2025: Fake accounts inundate Koizumi support forums.
- 2024: LDP attributes losses to online foreign influence.
- Ongoing: Platforms urged to curb election falsehoods.
Implications for Democracy and Regulation
The scandal spotlights challenges: anonymity enables unchecked negativity, AI scales production, public funds potentially subsidize it. Calls grow for transparency mandates, AI labeling, and faster content takedowns. Takaichi's administration eyes counter-disinformation strategies, balancing free speech with fair play.
Stakeholders—from rivals demanding probes to tech firms facing pressure—highlight tensions. For voters, discerning fact from fiction becomes paramount, especially as youth engagement surges via unvetted channels.
Internationally, parallels emerge with U.S. and European deepfake woes, positioning Japan as a testbed for Asia-Pacific norms.

Looking Ahead: Takaichi's Digital Legacy
As probes loom unlikely without new evidence, Takaichi refocuses on priorities: inflation curbs, defense bolstering, U.S. alliance deepening. Her social media edge—credited for electoral triumphs—now under microscope, potentially reshaping campaign norms.
Optimists see her denial fortifying trust; skeptics urge independent audits. Ultimately, this saga underscores digital media's double-edged sword: empowering direct democracy while risking its integrity. Japan's polity watches closely as Takaichi navigates this pivotal moment.
