Kasatka Bay, Natural bay in Iturup Island, Russia.
Kasatka Bay sits along the eastern coast of Iturup Island, fed by several rivers flowing into its sheltered waters. The bay features natural depth and width suitable for accommodating different types of vessels.
In early November 1941, the bay served as the launching point for a large Japanese naval fleet heading across the Pacific. This operation marked a turning point in the war.
The name of this bay reflects the island's history of shifting control between nations, each leaving traces in local names and stories. People living here have maintained deep ties to the water and fishing traditions that have shaped life for generations.
The bay is located in a remote area with limited accessibility by standard transport, and weather conditions can be harsh throughout the year. Visitors should prepare for isolation and self-sufficiency when planning to visit.
The bay was valued for its natural concealment, allowing ships to remain hidden from outside view during preparation periods. This geographical advantage made it a strategic choice for major operations.
