Youth-led Civic Innovation from Adachi, Tokyo
Step out of the audience.
Step into the story.
Give every teenager the chance to discover who they have yet to become
TEIGEN JP is a student-led organization building new ways for young people to take part in democracy, based in Adachi City — one of Tokyo's 23 special wards.
Figures as of July 2026. Definitions and sources are listed under Results and Recognition.
Founding Question
Who gets to meet the person
they have not yet become?
It is always the same people who speak up. The same hands go up; the same ones get chosen to represent everyone. Is that really all right? TEIGEN JP began in that unease. What we believe, in five chapters.
Two Pillars
Why civic education and cleaning?
Civic education builds the ability to take part in how decisions get made. Learning through community cleanup builds the feeling that the nearest piece of the public is yours to carry. We design them as one education, not two: how a person comes to see the society around them as theirs.
Civic education and youth participation
Wiring teenagers into the rooms where decisions get made.
The Mock Ward Mayoral Election, the Mock Gubernatorial Election (in concept), outreach classes, and a youth council model (in concept). Thinking policy through, arguing it out, and standing to be chosen yourself.

The nearest piece of the public, in your own hands.
Osouji-tai: Protect Your Neighborhood. Putting your classroom and your town in order with your own hands is where responsibility for society starts.

A Question Can Move Society.
A small unease you cannot yet put into words meets other people, becomes a TEIGEN, and moves society. The five powers of a question, as we understand them.

Expansion & Base Map
From Adachi to Tokyo.
And then to every town.
We work primarily online, with three physical bases in Tokyo for general meetings, working sessions and events. Each new region gets the model redesigned for its own context — one more circuit for young people to take part, at a time.

FROM A QUESTION TO A SYSTEM
One person's question,
turned into someone else's opportunity.
Adachi City, 2023.
In a climate where nothing was expected to change, one 15-year-old could not shake the feeling that something was wrong.
Why should the chance to think about society and act on it depend on where you happen to grow up?
Three friends from the same neighborhood answered that question with him. One person's unease became four people's resolve, and TEIGEN JP began.
What we set out to build was not a place where politics is explained to you. It is a place where teenagers raise their own questions, draft policy, face opinions they disagree with, and finally choose for themselves — where the decisions a society makes become your own problem to solve.
Read what happened next
The first Mock Ward Mayoral Election did not end as a one-off event. High school students who had taken part came back to build the next one, and partnerships with local government, schools and companies followed. What began in Adachi is now spreading to Setagaya and to Tokyo as a whole.
That way of learning — ask, think, work with others, act — has since moved beyond civic education into new practices, starting with learning through community cleanup.
An organization that began with four people is now38.
Through our work so far we have reached1,000 people with opportunities to learn and to argue things out.
But the number we most want to grow is not participants, or programs.
It is this: the person who received an opportunity creates the next one for someone else.
That cycle is the point.
TEIGEN JP is not built to preserve its founder's intentions. It is built so that each generation can take the question it inherits, ask it again in its own words, decide for itself, and rebuild the practice around it.
One person's question is becoming something other than an answer to hand down. It is becoming the machinery that lets the next person start asking.
The next chapter belongs to the next Questioner.
Four turning points
Scenes
The room, not just the record.
A question appears, becomes an argument, becomes policy, becomes a speech and then a vote. One day, in six scenes. Choose a photograph to open it.
