What is Fuupu River・Yamato Water?
The Background of Hundred Select Waters Designation
Fuupu River・Yamato Water was designated as one of the “Hundred Select Waters” selected by the Environmental Agency (now the Ministry of the Environment) in 1985 (Showa 60). The Hundred Select Waters is a system designed to preserve clear water environments throughout the country and to widely communicate their value. Within Saitama Prefecture, only this Fuupu River・Yamato Water was selected, making it highly regarded as a representative spring water of the prefecture.
The reasons for designation include the excellent purity of the water quality, abundant spring water volume, long-term conservation efforts by local residents, and high historical and cultural value.
Geographic Features and Water System
Fuupu River is a first-class river in the Arakawa water system flowing through Yorii Town, Osato District, Saitama Prefecture. It takes Yamato Water, which springs forth from beneath a large rocky cliff called “Hyakujou-shiki Rock” located on the north side of Mount Kamabuski (elevation 582m), as one of its main sources of flow, merging with seven tributaries while flowing approximately 6km before emptying into Lake Tamayodo (Arakawa).
The basin is included in the Nagoro Tamayodo Nature Park, where a rich natural environment is preserved. Along the stream, scenic spots such as Ookamibuchi (wolf’s deep pool) and Meotodaki (spouse’s waterfall) dot the landscape, allowing visitors to enjoy beautiful scenery in each season.
Spring Water Volume and Water Quality Characteristics
The spring water volume of Yamato Water is said to be approximately 10 to 70 tons per day, and according to some accounts, as much as 5,000 tons, constituting a stable water source that has never dried up since ancient times. The water that springs forth from beneath the Hyakujou-shiki Rock is groundwater that has permeated through the rock layers of Mount Kamabuski over many years, maintaining high purity through natural filtration processes.
The water temperature remains nearly constant throughout the year, remaining cold even in summer and not freezing even in winter. This stability in water temperature was one of the reasons it was highly valued as cocoon silk-drawing water in the region’s sericulture industry. It is characterized by being balanced in mineral content and having a mellow taste.
The Legend of Yamato Takeru and Historical Background
The Origin of the Name “Yamato Water”
The name “Yamato Water (やまとみず)” derives from the legend of Yamato Takeru (ヤマトタケルノミコト). This legendary hero, who appears in the “Kojiki” and “Nihon Shoki,” is said to have visited this area during his eastern campaign.
According to legend, Yamato Takeru prayed for victory in battle at the middle slope of Mount Kamabuski, and when he thrust his sword into the large rocky cliff called Hyakujou-shiki Rock to quench his thirst, clear water immediately sprang forth. Because the water was so cold that he could drink only one sip (one cup), it is also called “Ippai-mizu” (one cup of water).
Yamato Water Deity Enshrined at the Water Source
A shrine dedicated to “Yamato Water Deity” stands at the spring site, serving as an object of faith for the people of the region since ancient times. This deity is revered as a being that gives thanks for the blessings of water and protects the water source. Today, regular cleaning activities and religious rituals conducted by local residents continue the effort to pass on the spring water to future generations.
Local Life and Connection to Spring Water
Historically, Yamato Water and Fuupu River water have been deeply connected to the lives of local residents. In particular, in the Kanao district downstream of Fuupu River, there exists a well group called “Kanao’s Five Wells,” and the high-quality water has been used as drinking water and household water.
During the sericulture industry, which flourished from the Meiji era through the early Showa period, Fuupu River water was highly valued as cocoon silk-drawing water. The stable water temperature and pure water quality with few impurities were essential for producing high-quality raw silk.
