Leisure social theory was actively discussed in Japan from the 1960s to the 1980s. Among other things, leisure social theory in the 1970s functioned as a critique of industrialized leisure.On the other hand,ideas on the good uses of leisure which began in the pre-war period remained deeply entrenched and influential in the post-war period as well.In this paper,the definition of leisure time in the1960s and 1980s is analyzed from the perspective of leisure social theory discourse. Attention is given to the fact that self-realization as included in the definition of leisure was not actually a part of the ideas on the good uses of leisure and an attempt to critique this is made.
