Kamisesentou Spring Water (Kanagawa Prefecture) Complete Guide: Thorough Explanation of Access, Water Quality, and History
Kamisesentou spring water (Kamisesentou no yūsui), located in Hadano City, Kanagawa Prefecture, is a precious spring water spot created by the rich natural environment of the Tanzawa Mountain Range. The Hadano Basin is a treasure trove of spring water groups known as “Hadano Famous Water,” and Kamisesentou spring water is one of the water sources that has been cherished by local residents for many years.
In this article, we will explain in detail the characteristics of Kamisesentou spring water, access methods, nearby tourist spots, and Hadano’s spring water culture.
What is Kamisesentou Spring Water?
Kamisesentou spring water is a natural spring that flows out in the Sentou district of Hadano City, Kanagawa Prefecture. Hadano City is known as a “Town of Famous Water” and has spring water groups selected by the Ministry of the Environment for the “Top 100 Famous Waters.”
The Mechanism of Spring Water in the Hadano Basin
Spring water in the Hadano Basin is created when rainwater that falls in the Tanzawa Mountain Range permeates underground over a long period and emerges after undergoing natural filtration. Through this process, the water becomes rich in minerals and emerges as clear, delicious water.
The geology of the Tanzawa Mountain Range is primarily composed of volcanic rocks and sedimentary rocks, which function as a natural filter. Rainwater permeates deep underground and slowly moves toward the basin over several years to several decades before emerging at the surface.
Characteristics of Kamisesentou Spring Water
Kamisesentou spring water maintains a stable temperature throughout the year—cool in summer and relatively warm in winter. Generally, spring water temperature remains stable at around 15 degrees Celsius year-round, which is characteristic of groundwater.
The water quality is clear, and it has been used as daily water for local residents since ancient times. However, boiling is recommended before drinking.

Kamisesentou Spring Water Across the Four Seasons
Spring Landscape
When spring arrives, plants around the spring water bud, and the season of beautiful fresh green leaves begins. During cherry blossom season, you can enjoy walks combined with nearby cherry blossom avenues.
As spring snow melts, more water permeates underground, with a tendency for spring water volume to slightly increase. Water temperature remains cold, and you can feel a refreshing coolness.
Summer Landscape
Summer is a season when the coldness of spring water feels pleasant. While water temperature remains stable year-round, the difference with air temperature increases, making it feel particularly cool.
On hot days, areas around spring water become busy with people seeking cool relief. However, water play requires consideration for the surrounding environment and other users.
Autumn Landscape
Autumn is a beautiful season with surrounding trees turning colors and the contrast between fall foliage and spring water. The air is clear, and water transparency feels heightened.
After autumn rains, spring water volume may increase, with stronger water flow.
Winter Landscape
In winter, spring water temperature is higher than the air temperature, creating steam-like water vapor rising from the area. This is evidence that spring water temperature remains stable year-round.
On cold days, frost may form around the spring water area, creating a mystical landscape.

Risks of groundwater contamination from domestic and agricultural wastewater exist. Proper wastewater treatment and environmental conservation activities are important.
Climate Change Impact:
Changes in precipitation patterns due to climate change may affect spring water volume. Long-term perspective countermeasures are necessary.
Future Initiatives

Green Infrastructure Promotion:
Promotion of “green infrastructure” that infiltrates rainwater underground. Initiatives include introduction of permeable pavement, rain gardens, and biotopes to restore natural water circulation.
Watershed-Wide Conservation:
Spring water is part of the water circulation of the entire watershed. Comprehensive initiatives are being promoted from forest conservation in the Tanzawa Mountain Range to improvements in urban water environment.
Promoting Citizen Participation:
