Who is Takahiro Anno?

A Japanese AI engineer, entrepreneur and science fiction writer. In the 2024 election for Governor of Tokyo, he ran a campaign that used AI and broad listening to hear voters' voices. The next year he founded the party Team Mirai, became its leader, and has served in the House of Councillors. The book *Plurality* cites him as an example.

One of the things that made the word Plurality widely known in Japan was the 2024 election for Governor of Tokyo. This is the candidate who used AI in that election to gather voters' voices. The book Plurality also takes up that campaign as an example.

In short

Takahiro Anno (安野貴博) is a Japanese AI engineer, entrepreneur and science fiction writer. He ran in the 2024 election for Governor of Tokyo, and tried to turn the campaign period from a time when the candidate talks one way into a time for listening to voters with the help of technology [1]. He then founded the party Team Mirai, became its leader, and has served in the House of Councillors (the upper house of Japan's parliament) since 2025 [2].

At the press conference announcing his candidacy, Anno described his work as three things: a software and AI engineer, the head of an AI startup, and a writer, mainly of science fiction [1]. In fiscal 2015 he was selected for IPA's Mitou program and recognized as a "Super Creator" [3][4].

Connection to Plurality

An example in the book. Chapter 5-4 of the book, "Augmented Deliberation", presents Anno's work in the governor's election as "a [sic] interactive form of 'broad listening'" (the book's wording). He published his manifesto (list of policy promises) online, gathered opinions through X, Google Forms, AI-handled phone calls and GitHub, made the spread of views visible with Talk to the City, and ran an AI avatar, "AI-Anno", on YouTube that answered questions around the clock [5]. A footnote adds that his 150,000 votes were 2.3% of the total and put him in fifth place, the most votes ever for a candidate in their 30s in the 22 past Tokyo gubernatorial elections [5].

Chapter 3-3 of the book names Anno as one of the Japanese engineers whom Ken Suzuki's vision of the "Nameraka Society" continues to influence [6].

Links with Audrey Tang. At the press conference announcing his candidacy, Anno said he had consulted Audrey Tang about running. According to Anno, Tang said she liked his approach of combining broad listening, the My Number system (Japan's national ID numbers) and the spirit of open source [1]. Since then he has shared the stage with Tang at a 2024 event and at the Code for Japan Summit [7][8].

The word Plurality. In an interview with AERA, Anno named, as one of the ideas he values, the pair "Plurality" and "Singularity". If the Singularity is about how fast technology advances, he explained, Plurality is about thinking how society deals with technology [9]. In 2025 he also released an explainer video, "16分でわかる PLURALITY" (PLURALITY in 16 minutes) [10].

Main ideas

Broad listening. Turning the campaign period from a time for broadcasting the candidate's views into a period for listening to people's views. He said this at the press conference announcing his candidacy [1]. → Broad listening

A manifesto everyone can fix. In June 2024 he started a "participatory manifesto" on GitHub, where anyone could propose improvements or changes to his policies [11]. The number of accepted proposals is counted differently in different sources. The campaign staff's review says 72 of the 104 change proposals were merged [12], while Anno's own review and the footnote in the book say 85 of the 104 were adopted [13][5]. → Takahiro Anno's 2024 Tokyo campaign

Digital Democracy 2030. He announced its launch at a press conference in January 2025. Its stated aims are to advance broad listening, to reflect the public will in policy through large-scale forums for discussion, and to make political funding transparent, all as open-source systems anyone can use for free [14]. In March of that year, Kouchou AI (広聴AI; kouchou is the Japanese word for listening to the public, and the English edition of the book Broad Listening renders the name "Broad Listening AI") was released [15]. → Digital Democracy 2030

Team Mirai. The party was founded in May 2025 [16]. In the House of Councillors election that July it won one seat (Anno's) and met the legal requirements for a political party [2], and in the House of Representatives election of February 2026, 11 of its candidates were elected [17]. It works on its manifesto with "Idobata", which lets people propose policy changes through a dialogue with AI [18].

What is debated

Reflections by those involved

Who decides in the end? In his review of the governor's election, Anno writes that he believed a manifesto one can take responsibility for cannot be made by today's AI or by simple majority vote, so he decided himself which proposals to take in. He then writes that who finally decides and how, and how to deal with ideology, emerged as open questions, and refers to a point raised by the critic Hiroki Azuma [13]. According to the announcement of an event at Genron Cafe, Azuma, while praising Anno's election strategy, asked whether someone seriously aiming to be a politician should think more not only about technology but also about ideology. The announcement says this question would be taken up again at an event on September 18, 2024, with Anno and Daisuke Katsura (CTO of Shirasu, the service that streams the event) [19].

GitHub is not for everyone. Anno himself acknowledges that GitHub is not easy for everyone to use. He also writes that the phone version of AI-Anno was set up in a hurry after hearing that some people do not use YouTube [13].

Criticism from outside

Expecting too much of AI. Writing in the magazine Wedge (October 30, 2024), Azuma credited Anno with making a mark on elections. While in favor of bringing AI into public administration, Azuma argued that the idea that politics could be made semi-automatic (what Azuma calls "artificial intelligence democracy") is dangerous, and that expecting too much is a mistake [20].

Will Team Mirai's Plurality be only a label? A note article by a member of the public (October 2025) argues that the Plurality the party puts forward is all ideals with no institutional design, and that it is unclear who decides and who is responsible. The article also claims that the party has effectively discarded the manifesto change proposals it collected [21]. As for the numbers, a GitHub count on September 24, 2026 found 9,686 change proposals (pull requests) to the party's policy repository, of which 194 were merged [22]. The party says it accepts proposals that fit its mission and vision, agree with the broad direction of the manifesto and are feasible, and that AI is used to organize proposals while people decide whether to adopt them [23]. Criticism of the party is collected in the article on Team Mirai, and criticism of the book and its practice as a whole in Critiques of Plurality.
