History
The area of Mannō was part of ancient Sanuki Province. During the Edo Period,the town area was divided between the holdings of Takamatsu Domain, Marugame Domain and direct (tenryō) holdings of the Tokugawa Shogunate. The villages of Yoshino, Kanno and Shijo were established with the creation of the modern municipalities system on February 15, 1890. The three villages merged on April 1, 1955 to form the town of Mannō (満濃町). On March 20, 2006, Mannō absorbed the towns of Chūnan and Kotonami, both from Nakatado District and changed its name to its current hiragana spelling.

Nestled in the mountains, this lake reservoir is one of the largest in Japan, with a volume of 15,400,000 m3.[4] Kagawa has low rainfall, so rain dances and water reservoirs have been important throughout history, particularly for rice production.[5] The original dam was built about 1,300 years ago, from 701 to 704. In 821 the dam lay in disrepair and a larger version was built by the Buddhist monk Kūkai on the Emperor’s request. Since then the dam has fallen into disrepair and been rebuilt 3 times to reach its current size.
The water is used for rice paddy irrigation, and every year in June there is a ceremony to start the yearly flow. Four tonnes of water gush out every second to reach rice paddies as far away as Marugame City.
There is also a shrine and a temple near the lakefront.
