The Nemuro Strait is a narrow body of water located between the eastern tip of Hokkaido, Japan, and the Kuril Islands of Russia. It connects the Pacific Ocean to the Sea of Okhotsk and is approximately 43 kilometers long. The strait is known for its rich marine biodiversity and is an important area for fishing. The strait plays a significant role in regional shipping and navigation, serving as a route for vessels traveling between Japan and Russia. Its waters are also influenced by the cold currents from the Sea of Okhotsk, which contribute to the unique ecosystem found in the area.
