Sister Cities of Durham, North Carolina

Arusha, Durham-UK, Kavala, Kostroma, Toyama, Zhuzhou 

Toyama, Japan Sister City since 1989:  
Located on a delta plain between the Sea of Japan and the towering Southern Japanese Alps, Toyama was completely rebuilt after WW II bombing raids.  It is now a thriving modern metropolis and a "City of Medicine".

The "Mountains -- Waterways" connection is that Toyama lies at the base of the towering Southern Japanese Alps.
