自由民權運動
Hideko Fukuda was considered the "Joan of Arc" of the Freedom and People's Rights Movement in Japan during the 1880s. She was also an editor of "Sekai fujin" (Women of the World), a socialist women's paper that Shūsui Kōtoku contributed articles to. In 1885, Fukuda was arrested for her involvement in the Osaka incident, a failed plan to supply explosives to Korean independence movements. This plan was designed to destabilize Korea and force a confrontation between China and Japan, leading to a revocation of the treaties between the two. Before the plan was able to be implemented, the police arrested the conspirators and confiscated the weapons before they could leave Japan for Korea. Other participants in the plan included Oi Kentaro, another major figure of the Freedom and People's Rights Movement.
