Living here

A town with little rain and flat land made its land by reclamation.

  • about 50,000 people

In southwestern Okayama, the city borders Fukuyama, Hiroshima Prefecture, to the west. With no large river, it was prone to water shortages in dry summers; with the Kasaokawan reclamation project, a pipeline was laid from the Takahashi River, and tap water now reaches every household, islands included.
