ASSEMBLY IMPACT / ADACHI

Turn one day of listening to young people
into a record of assembly reform.

A Mock Ward Mayoral Election does not end when the event closes. An assembly can publicly record that it opened its chamber to young people and that members across party groups joined them in policy dialogue as a resident-participation initiative.

From the Adachi Ward Assembly published recordThe assembly held a student-run Mock Ward Mayoral Election and worked to advance civic education.

In the Waseda University Manifesto Institute Local Assembly Reform Survey 2023, the Adachi Ward Assembly ranked second among Tokyo special wards and 58th of 1,562 assemblies nationwide. The assembly itself records the Mock Ward Mayoral Election as a resident-participation reform carried out in 2023.

What is different afterward.

Participant satisfaction, Mock Ward Mayoral Election 2025 (out of 4.00)

Participants who said they wanted to vote in a real election (participant questionnaire)

For comparison: turnout among 18- and 19-year-olds at the 2022 House of Councillors election (Ministry of Internal Affairs and Communications)

* The 92% comes from a voluntary survey of participants; the 34.49% is an actual national turnout figure. The two were produced by different bodies from different populations, so they cannot be compared directly.

Impact

Measuring change, not counts.

We read our results on three levels: what we did, what changed in people, and what was left behind in society.

  1. OUTPUTWhat we did
    • Three editions of the Mock Ward Mayoral Election in Adachi (co-hosted with the Adachi Election Administration Commission since 2025)
    • Outreach classes in elementary, middle and high schools
    • Over 1,000 people reached across all programs, including outreach classes (as of July 2026)
    • Of which six events with 240 participants in total — three Mock Ward Mayoral Elections and three deliveries of Osouji-tai
    • 15+ partner institutions; 120+ council members and officials engaged
  2. OUTCOMEWhat changed in people
    • 92% of participants said they wanted to vote in a real election
    • Satisfaction of 3.73 out of 4.00 at the 2025 event
    • Participants coming back round to run it
    • A better grasp of drafting policy and deliberating, and more belief that they can affect things
  3. SYSTEM IMPACTWhat was left behind
    • Joint outreach classes with the Adachi Election Administration Commission, since March 2025
    • Ongoing working relationships with the ward office, the assembly and the board of education
    • The Mock Ward Mayoral Election is listed in the Adachi Ward Assembly published record as a resident-participation reform
    • Institutional research on a youth council model
    • Operating know-how standardized, and preparation for taking it elsewhere

Methodology

How we measure, and what we will measure next.

Current

How we measure now

Every program runs a participant questionnaire covering satisfaction, intention to vote and free comment, and every delivery is reviewed and its lessons recorded. Partner institutions and media appearances are counted annually and published with the date they were counted.

Next

What we are adding

Fixed-point measurement of how attitudes change between before and after; tracking what participants do afterward — voting, local activity, where they go next; systematic collection of assessments from host schools and government; and an annual report. All of it so that "we held it" is not the end of the sentence.

Next Step

The same thing, where you live.

Bringing the Mock Ward Mayoral Election or Osouji-tai to you, booking a speaker, press inquiries, sponsorship — tell us which and we will point you the right way.
