>>280172597The Japanese Archipelago Human Population Genetics Consortium8 produced ~900 000 genome-wide single-nucleotide polymorphism (SNP) data in the Ainu and the Ryukyuans, and through principal component analysis (PCA), and phylogenetic tree construction, demonstrated a clear genetic similarity between these two groups despite their current geographical locations at the opposite poles of the Japanese archipelago. Analysis of individual ancestry proportions and phylogenetic analysis of the Mainland Japanese also show that they carry both Ainu-Ryukyuan and continental Asian genetic components. A recent study that used a model-based approach was also in favor of the dual-structure model.9

>>280172605I was born and raised in west. So I only have a Japanese skin. In general Japan is nice, things are getting more expensive lately but I guess this is a global crisis with how everything is fucked up now (also weak yen makes imported shit more expensive)
