1960 Anpo protests were a nationwide wave of demonstrations and political actions in Japan from January to June 1960 opposing the revised Treaty of Mutual Cooperation and Security between the United States and Japan and the policies of Nobusuke Kishi's cabinet. The mobilization involved a coalition of Japan Socialist Party, Japan Communist Party, Sōka Gakkai, student groups like Zengakuren, labor unions such as Sōhyō, and civic organizations, converging on the National Diet Building and urban centers including Tokyo, Osaka, and Yokohama. The crisis culminated in mass protests, parliamentary clashes, and the eventual resignation of Nobusuke Kishi and reshaping of postwar Japan–United States relations.

Background

The negotiation and proposed ratification of the revised Treaty of Mutual Cooperation and Security between the United States and Japan under the administrations of Dwight D. Eisenhower in the United States and Nobusuke Kishi in Japan revived contentious debates rooted in the Occupation of Japan and the 1951 Treaty of San Francisco. Opposition coalesced around parties and organizations including the Japan Socialist Party, Japan Communist Party, Sōhyō, and student federation Zengakuren, while supporters included the Liberal Democratic Party and conservative media such as Yomiuri Shimbun and Asahi Shimbun. International context—marked by events like the Korean War aftermath, Cold War geopolitics, and U.S. military bases in Japan debates—intensified pressures on Prime Minister Nobusuke Kishi and influenced policy deliberations in the National Diet Building.

Timeline of events

January–March 1960 saw escalating demonstrations led by Zengakuren and labor contingents from Sōhyō, with major rallies in Tokyo's Hibiya Park and outside the National Diet Building; each protest drew activists from the Japan Socialist Party, Japan Communist Party, and civic groups like Sōka Gakkai. April featured a dramatic parliamentary confrontation when Nobusuke Kishi scheduled a rapid Diet vote on the revised Japan–United States security treaty, provoking a mass sit-in and the infamous "May 19 Incident" in which Kishi pushed the bill through the House of Representatives of Japan after LDP allies and police clashed with opposition members. May 1960 reached a peak with nationwide strikes organized by Sōhyō, student occupations at universities including University of Tokyo and Keio University, and the deployment of riot police, culminating in the "June Crisis" and Kishi's resignation on June 19 after enormous protests including the death of a female protester and the storming of the Diet precincts.

Political actors and public opinion

Key political actors included Nobusuke Kishi, Hayato Ikeda who succeeded Kishi as Prime Minister, leaders of the Japan Socialist Party such as Jōtarō Kawakami, prominent figures in the Japan Communist Party including Kenji Miyamoto, and labor leaders from Sōhyō like Kōzō Sasaki. Student leadership from Zengakuren and intellectuals associated with New Left currents, alongside conservative voices in LDP factions, shaped tactical debates. Public opinion polls in urban centers like Tokyo and Osaka reflected widespread popular unease with the revised Treaty of Mutual Cooperation and Security between the United States and Japan and Kishi’s methods, while foreign governments including United States Department of State officials and figures such as John Foster Dulles monitored the crisis closely.

Protest tactics and key incidents

Protest tactics combined mass rallies, sit-ins, parliamentary obstruction, general strikes, student university occupations, and creative direct action; groups on the left coordinated through networks linking Zengakuren, Sōhyō, and the Japan Socialist Party. Notable incidents included the May 19 forced passage of the treaty in the House of Representatives of Japan—the "May 19 Incident"—and violent clashes outside the National Diet Building during the June demonstrations that left several injured and one civilian fatality, which intensified calls for Kishi’s resignation. Labor actions by Sōhyō shut down transport in ports like Yokohama and industrial centers such as Kawasaki, while intellectuals and journalists from outlets like Asahi Shimbun and Mainichi Shimbun amplified coverage that mobilized broader urban middle-class participation.

Government response and consequences

The government's response, orchestrated by Nobusuke Kishi with support from LDP factions and law enforcement agencies such as the National Police Agency, combined legal maneuvers in the National Diet Building with forceful policing and attempts at negotiation involving diplomats from the United States including representatives of the U.S. Embassy in Tokyo. Consequences included Kishi’s resignation and the succession of Hayato Ikeda, adjustments to Japan–United States relations and treaty implementation, fracturing within the LDP that influenced later factional politics, and a strengthened activist network that affected subsequent movements like the 1968–69 Japanese university protests.

Legacy and historical significance

The protests reshaped postwar Japanese politics by demonstrating the potency of coordinated action by Zengakuren, Sōhyō, and the Japan Socialist Party, influencing the rise of conservative economic policies under Hayato Ikeda and the Income Doubling Plan, and altering public perceptions of Japan–United States relations and base politics centered on installations such as those in Okinawa. Historians link the movement to later social movements including the New Left and the Beheiren anti-war coalition, and to debates in scholarship involving figures like Chalmers Johnson and institutions such as Harvard University that studied Japan’s Cold War trajectory. The 1960 events remain a focal point in comparative studies of postwar democratization, protest movements, and transpacific security arrangements.
