Miyagase Dam is well-known as a great sightseeing and date destination, and people flock to it throughout the day to watch its discharges of water. But it is the colorfully illuminated nighttime outflow that is truly unique. The splendid combination of lights and the strong discharge makes this a popular attraction.
A water discharge show takes place on limited days from April to November. Prior application for the lottery to attend the night discharge show in October is required.
