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.
