Geography.
The Akiha hill extends to the south of the city, surrounded by plains. The city is located between the Shinano River on the east side, and the Agano River on the west side. The Niitsu River (Noudai River) flows between these rivers through the middle of the city, until it reaches the Koagano River, a small body of water that connects the Shinano and the Agano rivers. The Small Agano River flows outward from the mouth of the Niitsu, emptying into both the Shinano and Agano Rivers.
