It is each person's question
that keeps this place moving.
TEIGEN JP brings together 38 members from 22 high schools and universities across Tokyo and its three neighboring prefectures (as of June 2026). From the Mock Mayoral Election co-hosted with the Adachi City Election Administration Commission to visiting lessons at elementary schools, these members run everything from planning to the day itself.
