Under the mission "Give every teenager the chance to discover who they have yet to become," TEIGEN JP is a student organization that starts from the gap in who gets opportunities and works on young people's participation in society and on citizenship education. Founded in Adachi, Tokyo in 2023, it is planned and run by around forty high school and university students from Tokyo and the three neighboring prefectures. Its programs include the Mock Ward Mayoral Election, held in a ward office and assembly chamber reserved for the day; Osouji-tai, which builds awareness of public space through cleaning; and outreach classes run with government and educational institutions, giving more than 1,000 people in total a chance to learn democracy firsthand. It presented a policy proposal to former Prime Minister Kishida at the Prime Minister's Office, and its honors include first place nationwide at the National High School Policy Championship (supported by the Cabinet Office and the Ministry of Education) and the NHK President's Award at the High School Students' Speech Contest (hosted by the United Nations Association of Japan).
