The correlations between neurocranial measurements were examined by principal component analysis and Kaiser's normal varimax rotation methods to clarify which neurocranial sub-structures are the major source of the variations in maximum cranial length and breadth as a step toward elucidating the causes of brachycephalization. The results obtained from 30 male and 20 female modern Japanese show that cranial length is significantly associated with glabello-lambda and nasion-lambda lengths in both sexes and that cranial breadth is significantly associated with maximum frontal and biauricular breadths as well as with many cranial height measurements, but not with minimum frontal or biasterionic breadth across the sexes. Although the association between cranial length and the inion-opisthion chord, which was suggested to be strong in previous studies, was not significant at the 5% level, the present and previous findings still suggest that the variation in the occipital bone or the nuchal planum may be one of the causes for the variation in cranial length, and in turn, for brachycephalization or dolichocephalization.
