Matsumae clan
During the Edo period (1603–1868), the ruling Tokugawa "shōgun" allowed the Matsumae clan ("Matsumae han" 松前藩) to settle in the Menashi region, which was then named Nemuro. According to the Matsumae clan's "Chronicles of Shiragi" ("Shiragi no kiroku" 新羅の記録), from the first year of the Genna era to about Genna 7 (1615–1622) the region's inhabitants (referred to as the Ezo-people, or "Ainu") traded with the Matsumae clan, noting that the Matsumae received 100 small boats worth of eagle feathers and sea otter pelts.
