Magazine 9 (マガジン9) was established in 2005, aiming to provide information and knowledge for constitutional discussion, specifically focusing on pacifism and security issues attributed to Article 9.
This project is composed of intellectuals, including Sang-jung Kang (political scientist) and Rika Kayama (psychiatrist). Most of the members are against revision of Article 9.
After the project's founding, its website has broadened its range of topics to deal with into other issues related to constitutionalism (Article 99) and right of life (Article 25) in the context of labor problems. The website provides all of its content, such as essays and demonstration information, for free.
