Egahata Water (Kagawa Prefecture) Complete Guide | Thorough Explanation of History, Access, Water Quality, and Surrounding Tourism
Kagawa Prefecture is a region that receives relatively little rainfall nationwide and has long suffered from water shortages. In such Kagawa Prefecture, one of the precious water sources that has supported the lives of local residents is “Egahata Water.” This article provides a detailed explanation from a local perspective, covering everything from the historical background of Egahata Water to its current situation, access methods, and nearby attractions.
What is Egahata Water?
Egahata Water is one of the spring waters or water sources that exists in Kagawa Prefecture and has long been utilized as an important daily water supply for local residents. Kagawa Prefecture belongs to the Seto Inland Sea climate zone, and since its annual precipitation falls far below the national average, such spring water and well water have been cherished throughout history as precious water resources for the region.
Water Conditions in Kagawa Prefecture and the Importance of Egahata Water
Kagawa Prefecture’s annual precipitation is approximately 1,100mm, which is only about 65% compared to the national average of approximately 1,700mm. For this reason, Kagawa Prefecture has long been known as a “water-shortage prefecture,” and it is also famous for having the largest number of reservoirs in the nation.
In such a water-scarce environment, groundwater and spring water have played extremely important roles for local residents. Egahata Water, as one such regional water source, is believed to have supported the lives of local people over many years.
History and Origins of Egahata Water
Origins of the Place Name “Egahata”
The place name “Egahata” is found in several regions within Kagawa Prefecture. Generally, “Egata” refers to waterside or coastal areas, and “Hatake” refers to cultivated fields, suggesting it was a farming area close to water.
Historical Background
From the Edo period through the Meiji era, Kagawa Prefecture constructed many reservoirs as measures against water shortages. Simultaneously, spring water and well water were carefully managed as precious water sources. Egahata Water is believed to have been utilized as daily water supply for local residents within this historical context.
Particularly, there was high demand for agricultural water, playing an important role in rice cultivation and vegetable farming. Additionally, it was quite possibly used as drinking water, and may have been a central location for the regional community.
Characteristics and Water Quality of Egahata Water
Characteristics of Spring Water
Spring water in Kagawa Prefecture is generally formed when rainwater that has fallen on mountains such as the Sanuki Mountains permeates the ground and seeps out after being filtered through rock layers over long periods of time. For this reason, in many cases it becomes clear, cold water with appropriately balanced mineral content.
Egahata Water is likely water that has undergone such natural filtration processes, and is believed to have unique water quality characteristics determined by the region’s geological conditions.
