A total of 21 samples of germplasm which consist of 10 samples of wild soybean, 5 of wild azuki bean, 2 of weedy azuki bean, and 4 of Vicia spp. were collected. Wild soybean was found in every prefectures visited, whereas wild azuki bean was not found in Iwate, Aomori and the northern part of Akita prefectures (the northern part of Tohoku region). The northernmost collection site of wild azuki bean was Yokote, Akita prefecture (Site No. 56). A weedy azuki bean collected in Yonezawa, Yamagata prefecture (Site No. 60) had pale brown pods containing tan seeds, which differs in color from the other samples of wild and weedy azuki bean (brown pods with black mottled seeds).
