Abstract
This data article features a figure and tables that show the correlations among brand value by Brand Valuation (Interbrand Japan, Inc. Tokyo, Japan), market capitalization, and the consolidated overseas sales ratios of Japanese companies. The figure shows the scatter plot for market capitalization vs. brand value for Japanese companies. The lines in the plot show the regression fits for two groups of companies (domestic and global) with consolidated overseas sales ratios below or above 30%, respectively. The Pearson's correlation coefficients between brand value and market capitalization are calculated for global and domestic companies separately. Additionally, cross-tabulation statistics and Chi-square test of independence for brand values and consolidated overseas sales ratios were performed to assess their correlation.
