The artificial Otarunai lake was named by the citizens after an offer for public input was addressed. In 1994, the Otarunai Lakeside Park opened to the public and the Asari Dam Memorial building was constructed. It is also possible to walk on the dam during open hours. A tennis court and recreation facility were also completed. An Onsen is also located downstream from the dam.
