As John Cage wrote in his bookA Year from Monday, the “current use for art [is] giving instances of society suitable for social imitation—suitable because they show ways . . . people can do things without being told or telling others what to do.” Cage's ideal anarchic music emphasizes not only renouncing compositional control, but also the process of self-discovery happening to everyone, a process that leads participants to discover their creative abilities. This paper argues that Cage's penchant for self-discovery came from his understanding of George Herbert Mead's theories of the process of individuation (the “me” and the “I”). Cage discovered Mead through readingZen and American Thought(1962) by his friend Van Meter Ames, a professor of philosophy at the University of Cincinnati, who saw the compatibility between Zen and Mead's concept of self in the capacity of the “I,” a phase of self whose unpredictable steps contribute to human innovation. Cage found the possibility of overthrowing the thought of the world through triggering a self-discovery of the “I” in everyone. He realized this idea in his happenings, such as0’00”, by requiring performers to respond to the simple descriptions without specifying sound or duration.

After Cage and Tudor visited Japan in 1962, the term ‘Cage Shock’ circulated widely among the Japanese public. My interviews with Japanese composers suggest that the term ‘Cage Shock’ oversimplifies the reception of Cage's debut in Japan. Composer Yūji Takahashi stated that Cage would have met Japanese audiences well prepared for his visit by musical trends present in Japan as early as the late 1940s. Building on the statement that the Japanese avant-garde was thriving before Cage visited Japan in 1962, this article aims to deconstruct the term ‘Cage Shock’ by restoring the complexity of the reception of Cage in Japan and by analysing the reasons why critics adopted the term ‘Cage Shock’. I argue that ‘Cage Shock’ has functioned more as a media buzzword that sensationalizes the story of Cage's impact on Japan than as an objective description of Japanese reaction to Cage.
