Nakagawa Town in northern Hokkaido lies between the Kitami and Teshio mountains, along the majestic Teshio River. Its fertile plains greatly support agriculture. The climate features dry springs, wet autumns, severe cold, and heavy winter snow. Known as a "fossil town," it boasts widespread Cretaceous strata yielding beautiful ammonites.
