In 1968 and 1969, Japanese universities were wracked by student protests that ultimately forced the closure of campuses nationwide. Known as daigaku funsō or daigaku tōsō, the protests were part of the worldwide protest cycle in 1968 and the greater late-1960s Japanese protest cycle, including the Anpo protests of 1970 and the struggle against the construction of Narita Airport. Students initially demonstrated against practical issues in universities, and they eventually formed the Zenkyōtō in mid-1968 to organize themselves. The protests were dispersed in 1969 by the Act on Temporary Measures concerning University Management.

Masamune (正宗), also known as Gorō Nyūdō Masamune , was a medieval Japanese blacksmith who is widely recognized as Japan's greatest swordsmith. He created swords and daggers, known in Japanese as tachi and tantō respectively, in the Sōshū school. However, many of his forged tachi were made into katana by cutting the tang (nakago) in later times. For this reason, his only existing works are katana and tantō. No exact dates are known for Masamune's life. It is generally agreed that he made most of his swords between 1288 and 1328. Some stories list his family name as Okazaki, but some experts believe this is a fabrication to enhance the standing of the Tokugawa family.

The Allied Occupation of Japan was a military occupation of Japan in the years immediately following Japan's defeat in World War II. Led by the United States with the support of the British Commonwealth, the occupation lasted from 1945 to 1952 and involved a total of nearly 1 million Allied soldiers. The occupation was overseen by American general Douglas MacArthur, who was appointed Supreme Commander for the Allied Powers by President Harry Truman; MacArthur was succeeded as Supreme Commander by General Matthew Ridgway in 1951. Unlike in the occupation of Germany, the Soviet Union had little to no influence over the occupation of Japan, declining to participate because it did not want to place Soviet troops under MacArthur's direct command.

The Treaty of San Francisco , also called the Treaty of Peace with Japan , re-established peaceful relations between Japan and the Allied Powers on behalf of the United Nations by ending the legal state of war and providing for redress for hostile actions up to and including World War II. It was signed by 49 nations on 8 September 1951, in San Francisco, California, U.S. at the War Memorial Opera House, with three member states refusing to sign: The Soviet Union, Poland and Czechoslovakia, all part of the Soviet Bloc, and a further two states refused to send representatives: India and Yugoslavia. Italy and "China" were not invited, the latter due to disagreements on whether the Republic of China or the People's Republic of China represented the Chinese people. Korea was also not invited due to a similar disagreement on whether South Korea or North Korea represented the Korean people.

The name of the protests comes from the Japanese term for "Security Treaty," which is Anzen Hoshō Jōyaku (安全保障条約), or just Anpo (安保) for short.
