The area around Kasamatsu was part of traditional
Owari Province until the course of the Kiso River shifted in 1586, after which time it was part of
Mino Province. It was an ancient settlement on the important river crossing connecting
Nagoya with
Gifu. During the
Edo period, it was mostly
tenryō territory controlled by
Tokugawa shogunate through a
bugyō. During the post-
Meiji restoration cadastral reforms, the area was organised into Haguri District, Gifu Prefecture, which was subsequently transferred to
Hashima District, Gifu. The modern town of Kasamatsu was formed on July 1, 1889. In expanded by annexing the neighbouring village of Matsueda on August 1, 1950, and the village of Shimoharugi on April 1, 1955. Plans to merge with the neighbouring city of Gifu were rejected by a referendum in June 2004. ==Economy==
