AbstractThis paper analyzes the culture history of the little-known Okhotsk culture and makes suggestions about its relationships with neighboring cultures. The Okhotsk culture is important in understanding the cultural history of the northern Pacific because it shows no affinities with the Ainu and Japanese cultures and has an economy remarkably like that of the more distant Aleut and Eskimo. The Okhotsk culture appears to have historical relationships with cultures in Siberia and Manchuria. The maritime hunting economy of this culture was probably derived from the Eskimo via Bering Sea and the Siberian coast. Other cultural elements, the most noticeable being ceramics, were of mainland origin and served as an influential force in forming Okhotsk culture. Once established on Sakhalin, this culture moved southward along the northeastern coast of Hokkaido, where a secondary and later cultural center developed. Migrations up the Kuriles occurred shortly thereafter. This culture probably flourished for at least a thousand years, beginning in Sakhalin several centuries before Christ and persisting until sometime after A.D. 1000 and possibly until the 17th century in the Kuriles. Several unsolved problems concerning the Okhotsk culture are presented.
