Wappara Canal


Wappara Canal村

A “warm water canal,” locally known as a “nurume,” made wider and shallower (16-18 meters wide, 10 cm deep) and winding back and forth so as to be exposed to plenty of sunlight, this was constructed to bring the cold water originating in the Northern Alps up to the right temperature for growing rice. It is said that a 1°C rise in water temperature increases the rice yield by 1 bale, and this canal is able to raise the temperature 2°C over a distance of 300 meters.
There are also arbors and walking paths, and children can enjoy playing in the water there.
