Here is natural spring water that never runs out throughout a year. This spring water was discovered for the first time in 1973 (Showa 48th) when a forest road had been exploited. There is also "Ajisai-no-Komichi (Alley of Hydrangea)" near this spring water where Ajisai flowers fully bloom along the forest road when they are in season, providing you with a relaxing time in the nature.
