The Japanese input-output tables for 1975, 80, and 85 with 175 endogenous sectors were triangulated using the algorithm of Simpson and Tsukui. The degree of obtained triangularity measured by a linearity index is about 0.9, and indicates the existence of significant hierarchy among 175 industries. Rank correlation coefficients of sectoral orderings are about 0.98, and indicate stability of the hierarchical structure over time.
