The town was founded in 1559 in a small mountain valley next to the Nagara River. Here, two fast-running rivers, both tributaries of the Nagara River, create a natural moat around an area at the foot of a small mountain – known locally as Mount Hachiman. Over time, a small town blossomed and grew in this protected area below the castle.
