Anju

Anju lay in the Ussuri region, where forested mountains and tributaries connect the Sikhote-Alin with the Amur basin. The Ussuri freezes during the cold season, and snowmelt and rain contribute to seasonal floods. Rivers and their valleys have long provided routes through this northern landscape.

Udege and other Tungusic-speaking communities lived in the wider region, drawing on its forests and waterways.
