The purpose of this study was to assess the extent to which the Japanese sport industry was affected by business fluctuations in the domestic economy during the 1986-1993 business cycle. In addition, the relations between changes in the general economy (gross domestic product, combined sector in the economic activities, family income, living expenditures, and working hours) and the value of the sport industry were investigated. The annual figures for these variables were derived from several government and nongovernment publications, and the percentage changes in these variables were used in multiple regression analysis. Analysis indicated that the trend in value of the sport industry was affected by the fluctuations and demonstrated positive correlation with the changes in the combined sector in the general economy. However, the trend in value of the sport industry was not correlated with trends in family income or living expenditures during the period under observation. Subsequent analysis of the sportswear sector in the sport industry demonstrated negative correlation with working hours.
