A sluice to regulate the water level of Lake Inawashiro in order to allow water to flow to the Asaka Plain. This was the first project of the irrigation works in Asaka to have been started. It was constructed with 16 stone arches back then, making it one of the biggest sluice gates in Japan at the time. This is a symbolic structure of the Asaka Land Development Project and Asaka Canal construction works, and there are stories that the monk Kukai made 16 mounds for people to pass through the canal, relieving the townspeople from inconvenience.
