On June 5, 2008, the Ministry of the Environment announces Japan’s 100 Best Spring Waters of the Heisei Era (平成の名水百選) and four of them are in Shiga Prefecture including one in Aisho-cho: Yamabiko Yusui (山比古湧水) in Matsuo-dera. The 100 locations were selected based on the water’s quality, volume, and how well it was used and preserved by the community.
