What is "sekirankai"

The Sekirankai (赤らん会; Red Wave Society) was a Japanese socialist women's organization active in 1921. Members of an anarchist group established the organization in April 1921. Prominent feminists Yamakawa Kikue and Noe Itō were advisers for the group, which participated in that year's May Day activities, published the magazine Omedetashi, held seminars and lectures, and distributed anti-war leaflets to the army. Their manifesto condemned capitalism, arguing that it turned women into slaves and prostitutes. The Sekirankai was the first women's socialist association and clashed with Shin Fujin Kyōkai (the New Women's Association). The organization dissolved eight months after its creation.
