  Manno Lake

  One of the largest irrigation reservoirs in Japan, Manno Lake is said to have been created in the Daiho era (701–704). In the 12th year of the Konin era (821), the Buddhist monk Grand Master Kukai used the Tang dynasty’s latest engineering techniques to renovate the dam, completing Japan’s first arch dam in a short time. The new design boasted several times the strength of past dams. The dam has been further renovated and raised since that time, and now boasts a water storage capacity of 1,540 tons. Known as the “water jug of Sanuki” (an old name for Kagawa), these blessed waters of Kukai spread out over a vast area like an ocean.
