Abstract
Genomic studies initiated at the end of the 20th Century reached one peak when the human genome was sequenced. It was, however, not the end, but the starting point. Studies based on enormous numbers of SNP and microsatellite DNA polymorphism exploded, and a new light also shines on genetic diversity of people of Japanese Archipelago, while confirming results based on small scale classic polymorphic markers. Sequencing individual human genomes is also going on. These new horizon of human genomics was introduced.
