In this study, we investigated two chloroplast genome regions of Lathyrus japonicus Willd. in Hokkaido, thereby considering the possibility of utilization as locally sourced seeds. As a result, four haplotypes were detected throughout all survey sites, the haplotypes in one city and five towns were as follows : (1) In Ishikari city, Shinhidaka town and Urahoro town, all individuals had only haplotype A; (2) In Setana town, the individuals had two haplotypes, A and D at a ratio of 2:1; (3) In Okushiri town, the individuals had three haplotypes, A, D and E at a ratio of 7:4:4; (4) In Oshamambe town, the individuals had two haplotypes, A and C at a ratio of 5:2; (5) In Oume town, the individuals had two haplotypes, A and C at a ratio of 9:1. These results revealed that the main haplotype in Hokkaido was A, which matched the haplotype distributed from Hokuriku to Tohoku regions in the previous reports.
