Kanba was one of the 76 student activists who were arrested at a January 26, 1960 sit-in at Haneda Airport.[4] She also participated in protests around the Diet Building. She was killed just inside the South Gate of the National Diet Building after a group of students broke into the gate and clashed with riot police. An autopsy later determined that she died from chest compression and intracranial bleeding. Police claim that she was knocked down and trampled to death, while students blamed her death on physical assaults by police officers.
After her death, Kanba's personal writings and political essays were collected and published under the title "The Smile Nobody Knows" (Japanese: 人しれず微笑もん).[5] In her writings, she discusses her life and activism.
Kanba's death was widely covered at the time, and is seen as a symbol of the 1960 mass protests against the revised Treaty of Mutual Cooperation and Security Between the United States and Japan. A political cartoon that ran in the popular journal Sekai a month after Kanba's death depicted a yakuza gangster lighting a cigarette for a policeman as they both stand over her dead body in front of the National Diet Building.[6]
Historian Nick Kapur argues that nationwide shock at Kanba's death helped force the resignation of Prime Minister Nobusuke Kishi and the cancellation of a planned visit to Japan by U.S. President Dwight D. Eisenhower.[7] Kapur says Kanba's death was viewed as a "triple tragedy," first because she was so young, second because she was a student at Japan's most elite university, and third, because she was a woman, at a time when it was still novel for women to participate on the front lines of street protests.[8]Eiji Oguma has contended that Kanba's death evoked recent memories of the many young people who lost their lives in World War II.[9] Hiroko Hirakawa framed Kanba's posthumous status as a "maiden martyr" as reflecting contemporary expectations about middle-class femininity and motherhood.[10] Chelsea Szendi Schieder argues that the global 1960s began in Japan with Kanba's death.[11]
Photographer Hiroshi Hamaya captured the events of the night Kanba was killed.[12]
Akiko Esashi wrote a biography in Japanese on Kanba in 2010, under the title Michiko Kanba: Legend of a Sacred Girl (Japanese: 樺美智子ー聖少女伝説).[13]
