日本教職員組合

This union was founded in 1947 when three separate teachers unions combined to become the dominant teachers’ union in Japan. Since its establishment, the union has worked on anti-war movements, using the slogan “we will never send our students to any battlefields”.  They have been opposed to constitutional revision and urged Japan to keep the “Peace Constitution,” which stipulates the denunciation of war in Article 9. As for the security bills in 2015, the union protested the government, associating with other anti-war citizens’ groups, such as Rengō Heiwa Fōramu (連合・平和フォーラム),Anti-War Committee of 1000/Sensō o Sasenai 1000-nin Iinkai (戦争をさせない1000人委員会) and Rikken Fōramu (立憲フォーラム). They argued that Japan would participate in wars under security legislation that would allow Japan to exercise its collective self-defense right. Their statements and resolutions are available on the website.
