The castle was built by Lord Hineno from 1592 to 1598. It is the highest elevation flatland castle ever constructed in Japan. The castle is also known as a the "Floating Castle" because it was built on a small island in the lake that was connected to the shore by a narrow path of land. The lake now since a couple blocks West of the castle and is periodically dredged to maintain a consistent shoreline.
The Suwa clan had ruled over the area around Lake Suwa for hundreds of years but lost control in 1542. In 1601 they regained control and continued to rule until 1869. In the 1870's the castle was dismantled by order of the Meiji government.
