Daigo Fukuryū Maru
The public outcry against the government's handling of the "Daigo Fukuryū Maru", its crew, and the lack of information about fallout kindled an anti-nuclear and anti-American movement. After the ship docked and received national attention, municipal, prefecture and national assemblies passed resolutions in support of limiting or banning nuclear testing. After the death of Kuboyama, the movement expanded. In Tokyo, the National Council for a Petition Movement to Ban Atomic and Hydrogen bombs was founded. This group began an annual ban-the-bomb convention in 1955. At the first World Conference, a new organization called the Japan Council Against Atomic and Hydrogen Bombs formed to expand the movement and moved to include the hibakusha. The anti-nuclear movement eventually culminated in demonstrations against the United States-Japan Security Treaty in 1960.
