The original 1952 Security Treaty had established the U.S.-Japan Alliance, but did not put Japan on an equal footing with the United States. Among other provisions inimical to Japanese interests, the Treaty had no specified end date or means of abrogation. On May 1, 1952, just a few days after the Security Treaty came into force, protests were staged around the nation against the ongoing presence of U.S. military bases even though the Occupation had officially ended. The protests in Tokyo turned violent, coming to be remembered as "Bloody May Day."
