Mannō (まんのう町 Mannō-chō?) is a town located in Nakatado District, Kagawa Prefecture, Japan.

As of September 2011, the town has an estimated population of 19,933. The total area is 194.33 km².

On March 20, 2006, Mannō (満濃町) absorbed the towns of Chūnan and Kotonami, both from Nakatado District, to form the new and expanded town of Mannō (まんのう町).

Manno is located by the northern foothills of the Sanuki Mountain Ranges in southern Kagawa Prefecture. In the center of Manno is Manno Lake, the largest irrigation reservoir in Japan.

The town of Manno was formed on March 20, 2006, as a result of a municipal merger between the towns of Manno (満濃町), Chunan (仲南町), and Kotonami (琴南町). The written name of Manno was designated as まんのう町 at this time.

Nestled in the mountains, this lake reservoir is one of the largest in Japan, with a volume of 15,400,000 m3. Kagawa has low rainfall, so rain dances and water reservoirs have been important throughout history, particularly for rice production. The original dam was built here about 1,300 years ago, from 701 to 704 by Michimori Ason. In 821 the dam lay in disrepair and a larger version was built by the infamous Kobo Daishi (Kukai) 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.
