Okhotsk High Sea

The open Sea of Okhotsk connects Sakhalin and the northeastern Asian mainland with island passages toward the Pacific. Cold currents, seasonal ice, fog and storms make navigation demanding, while its waters support fish and marine mammals. Coastal communities use specialised tools and knowledge to gather resources and travel by boat between settlements and fishing places.

During the medieval and early modern centuries, Indigenous societies around Sakhalin and neighbouring coasts maintained social ties and exchange across waterways and river mouths. Furs, fish products, tools and cloth could pass through several intermediaries. Japanese, Qing and Russian commercial and political interests later overlapped across the wider region. Expeditions and maps increased outside knowledge, but finding food, landings and routes through these waters still depended on local experience.
