We determined the differences in carbon, nitrogen and oxygen isotopic compositions (δ13C, δ15N, and δ18O) between short grain rice samples from 9 locations (Hokkaido, Yamagata, Niigata, Nagano, Ibaraki, Tokyo, Mie, Hiroshima and Okinawa) in Japan to discriminate their geographical origin. Oxygen iso...
