The surrounding landscape is dominated by low-lying hills and slopes; much of the built town and residential areas are located in flatter land between the heights. The north of the town borders onto Uradome Beach, though much of the rest of the coast consists of rough rocky outcrops and small inlets and bays. 15 km of this, collectively known as the Uradome Coast, is part of the Sanin Kaigan National Park. The Gamō River runs through the centre of the town. Iwami is around 30 minutes by train from the prefectural capital of Tottori City, and is the third stop by train heading east on the Tottori-Hamasaka line. Hyōgo Prefecture and Iwami's sister town of Shin'onsen are relatively nearby as well.
