Isaka is a small town and station on the Mwanza railway line of Tanzania which connects to the seaport of Dar es Salaam. It is located in Kahama Rural District of Shinyanga Region. In the 1980s a so-called dry port was established there to serve the landlocked countries of Burundi and Rwanda, since Isaka is on a highway, now paved, running 610 km from the Rwandan capital, Kigali. The dry port functions as a sub-port of Dar es Salaam. Road transport companies can collect containers coming from overseas at Isaka and clear customs there, and deliver containers going overseas to the same location.
