HOME > Famous Pure Waters

In Oita Prefecture, there are the mountainous regions of Sobo Katamuki Mountain Ranges, Kuju Vo l c a n o Group, Mt. Hiko, Inugadake Mountain Ranges and the lava plateaus of Kusu and Yabakei. The spring sources in these regions have an abundant supply of clear natural water and are closely linked to the residents' lives. The mountain stream is part of the unique and beautiful scenery, and it brings visitors a sense of peace and relaxation every season. The water has been a source of life for marine creatures and a precious asset of the local residents. Their predecessors built a small shrine at the places where pure natural water sprang out and have offered the god of water their appreciation, awe and respect.
With the water problems of contamination and an aggravation in the quality of water, good and clear natural water is in high demand these days.
As the concern about water has been growing, Oita Prefecture selected particularly excellent water in the springs and streams of each locality in 1988. These selections were introduced as the "Famous Waters of Toyo-no Kuni" to appeal to the people's sense of closeness to water and to keep the water quality. The 15 "Famous Waters of Toyo - no Kuni" were examined using criteria such as clearness, quantity, surroundings, hydrophilic, preservative condition, usage, origin and history, rareness and uniqueness.
There are many excellent spring and stream waters in many places in Oita other than the qualified springs, and these are used in various ways by the residents and play an important role in supporting their lives.
