What is Kotsujikawaの Springwater?
Basic Information
Kotsujikawaの Springwater is a springwater site located in the Imaizumi district of Hatano City, Kanagawa Prefecture, and is known as a component of the Hatano Basin Springwater Group. The Hatano Basin is the only basin in Kanagawa Prefecture, and its special underground structure functions as a “natural water reservoir (groundwater basin).”
Location: Hatano City, Imaizumi, Kanagawa Prefecture
Classification: Part of the Hatano Basin Springwater Group
Characteristics: Springwater site surrounded by residential area, no water collection facility
About the Hatano Basin Springwater Group
The Hatano Basin Springwater Group is a representative springwater group in Kanagawa Prefecture, also certified as one of the “Heisei Top 100 Waters” selected by the Ministry of the Environment. Approximately 750 million tons of groundwater is stored beneath the Hatano Basin, and this abundant groundwater springs forth in various locations throughout the city.
The Hatano Basin Springwater Group includes, in addition to Kotsujikawaの Springwater, the following springwater sites:
- Ararai Springwater
- Imaizumi Springwater
- Jutokuji Springwater
- Mukohara Springwater
- Kawaramachi Springwater
These springwater sites have supported the region’s agricultural activities since the era when the Hatano Basin was a rural farming area, serving as agricultural water sources.
History and Geographical Background of Kotsujikawaの Springwater
Geological Structure of the Hatano Basin
The abundance of groundwater in the Hatano Basin is due to its unique geological structure. Rivers flowing from the Tanzawa Mountains and Hakone Mountains deposited sediment in the basin over long periods of time, forming highly permeable geological layers. This layer functions as a massive groundwater basin, storing precipitation and river water underground.
Groundwater follows gravity and moves toward the low-lying areas of the basin, rising close to the ground surface where it appears above ground as springwater. Kotsujikawaの Springwater is also part of this natural groundwater circulation, springing forth in the Imaizumi district.
Former Rural Landscape
The area surrounding Kotsujikawaの Springwater was once a typical rural farming area of the Hatano Basin. The springwater supplied water to nearby rice paddies and fields, serving as an important water source supporting agricultural production. The clear, pure springwater was suitable for rice cultivation and made a significant contribution to the agricultural development of Hatano.
Changes Due to Urbanization
From the latter Showa era through the Heisei era, the area south of Hatano Station underwent rapid urbanization. Rural farming areas were successively converted into residential areas through land development. While many springwater sites were buried or placed underground, Kotsujikawaの Springwater is one of the few remaining springwater sites preserved to the present day through the efforts of local residents and administration.
Current Status of Kotsujikawaの Springwater
Springwater Site Surrounded by Residential Area
Currently, Kotsujikawaの Springwater exists surrounded by residential areas. The vast rural landscape of the past is no longer visible, but the springwater site itself continues to flow with water. Due to the dense residential development in the surrounding area, the springwater site remains as a relatively small space.
Water Collection Facilities
Kotsujikawaの Springwater has no water collection facilities for the general public to draw water. This is because the springwater is primarily used as agricultural water downstream. While there are many other springwater sites in Hatano City, some have water collection facilities installed, allowing citizens and tourists to freely draw water. However, Kotsujikawaの Springwater prioritizes its role as a local agricultural water source, so no water collection facility has been provided.
Role as Agricultural Water
Kotsujikawaの Springwater currently continues to supply water to a small amount of remaining farmland downstream. Even as urbanization progresses, some agricultural land remains, and this springwater continues to function as a precious water source supporting agricultural production there. Without this springwater, agricultural activities on nearby farmland would become difficult, making it an important presence for the region.
Ecosystem Conservation
Springwater sites provide precious natural environments in areas where urbanization has progressed. Around the springwater, wetlands form, creating habitats for aquatic plants, insects, and small animals. As a small natural space within a residential area, it also contributes to the conservation of biodiversity.
