Human genomic similarities among four different regions of mainland Japan. a. Schematic diagram indicating the geographic origins of the Japanese samples used in this study. b. Scatter plot of first and second eigenvalues in principal component analysis (PCA) of genetic diversity in chromosome 1 of Japanese and other East Asian populations analyzed in the 1000 Genomes Project. Horizontal and vertical axes indicate the first and second components, respectively. The dots represent individuals and the legends are shown on the top right. C. PCA of the five Japanese populations analyzed in this study (close up view of Fig. 1b). The individuals used in the 1KJPN panel are indicated by small dots to improve the visualization of other populations
