Complete Guide to Yanagikawa District Wetland Spring (Hadano City, Kanagawa Prefecture) | Access, Features, and Surrounding Information
What is Yanagikawa District Wetland Spring?
Yanagikawa District Wetland Spring is a precious spring water site located in the western part of Hadano City, Kanagawa Prefecture. Hadano City is the only basin-shaped topography in Kanagawa Prefecture, and due to its unique underground structure, it serves as a “natural water reservoir” storing approximately 750 million tons of groundwater. This abundant groundwater springs forth at various locations throughout the city, and Yanagikawa District Wetland Spring is one of the places blessed by this water.
Yanagikawa District is a region where satoyama (semi-natural grassland) environments are distinctly preserved. Centered around this spring water, a nature conservation area called the “Living Things’ Village” has been formed. The spring has a history of use by local residents since the Showa era and is currently carefully protected by local conservation activity organizations.
Hadano Basin Spring Group and Japan’s One Hundred Select Waters
Yanagikawa District Wetland Spring is part of the Hadano Basin Spring Group, which is included in the Ministry of the Environment’s “Heisei One Hundred Select Waters.” The Hadano Basin Spring Group includes, in addition to Yanagikawa District Wetland Spring, Shungaku Spring, Kobo’s Clear Water, Gomayadashiki Spring, Imaizumi Wetland Spring, and several other spring sites. Each possesses its own characteristics while forming Hadano’s rich water environment.
The groundwater basin of Hadano City is formed when abundant precipitation from the Tanzawa Mountains permeates underground and is stored by the geological structure unique to basins. Through this natural system, stable water volume and high-quality water are maintained throughout the year.
Features of Yanagikawa District Wetland Spring
Satoyama Environment and Ecosystem
The greatest feature of Yanagikawa District Wetland Spring is its integration with the surrounding satoyama environment. Around the spring pool, deciduous forests, rice paddies, and small streams remain, maintaining a precious ecosystem in which diverse organisms live.
This environment has been developed as the “Living Things’ Village,” where a wide range of aquatic creatures such as dragonflies, frogs, medaka fish, and fireflies can be observed, as well as wild birds and insects. Particularly from spring through summer, various organisms’ activities become active around the spring pool and its surroundings, making it utilized by many people as a place for nature observation and environmental learning.
Water Quality and Volume
The water at Yanagikawa District Wetland Spring is clear and pristine rainwater that fell on the Tanzawa Mountains and, over a long period, naturally filtered through underground. Hadano City regularly conducts water quality surveys at spring sites throughout the city, and Yanagikawa District Wetland Spring is among the survey targets.
The spring water temperature remains nearly constant throughout the year, feeling cold in summer and relatively warm in winter. This stable water temperature provides a comfortable habitat for aquatic organisms. Water volume fluctuates seasonally; however, supported by the abundant groundwater of the Hadano Basin, a certain flow rate is maintained even during dry periods.
Historical Background
In Yanagikawa District, since the Showa era, spring water has been used by local residents as domestic water. Beyond agricultural use, it was cherished as an essential water source for daily life, including drinking water, washing, and other household needs.
In recent years, direct usage has declined due to changes in lifestyle, but the spring is now recognized with new value as a precious regional natural resource and as a place for environmental education. Local conservation activity organizations have taken the lead in conducting continuous cleaning of the spring pool, surrounding environmental improvements, and ecosystem protection activities, with efforts progressing to pass this precious natural environment on to future generations.
