The districts which soldiers were selected are unknown; as a diary by Toneri (palace servant) of Oama no Miko, ATO no Muraji Chitoko, quoted in "Shoku Nihongi" (Chronicle of Japan Continued), shows that soldiers were gathered in Shinano Province (belonged to Tosan-do Road), it is presumable that soldiers were gathered also in Kai Province which belonged to Tokai-do Road by later Taiho Ritsuryo (Taiho Code) as well.
徴兵範囲は記されないが、後の律令制では甲斐国は東海道に属し、『続日本紀』で引用されている大海子の舎人安斗連智徳の日記によれば信濃では徴兵が行われている。
