Niimi City is a mountain town in northwestern Okayama Prefecture, where the Takahashi River has its source.
Limestone plateaus stretch across the southeastern part of the city, dotted with limestone caves such as Ikurado Cave. In the medieval period, Niimi Manor, an estate of Toji Temple in Kyoto, was established here, and traditional cultural practices such as Watari Byoshi and taiko rice planting have been passed down. The history of washi papermaking also remains, and snow accumulates in the mountainous areas in winter.
