This article provides a detailed explanation of Kashomai’s Daishomizu, covering its historical background, water quality characteristics, connection to regional culture, and access methods—all concerning this precious named water.
What is Kashomai’s Daishomizu?
Kashomai’s Daishomizu is a spring water spot located in the Kashomai district of Kanazawa City, Ishikawa Prefecture. It is particularly well-known within Kanazawa City and, although not selected for the Ministry of the Environment’s “Heisei Selection of 100 Famous Springs,” continues to be beloved by local residents as a representative spring water of Ishikawa Prefecture.
Basic Information
Location: Kashomai 2-chome, Kanazawa City, Ishikawa Prefecture
Water Source: Groundwater (natural spring water)
Access Restrictions: Allowed (viewing, proximity, touching)
Usage Status: Continued use as domestic water by local residents
The Kashomai district is located slightly southeast of central Kanazawa City, surrounded by residential areas including Kashomai Honmachi, Kikugawa, Jonan, Hondamachi, Ishihiki, and Odarino. This area has been blessed with abundant groundwater since ancient times, and Daishomizu is known as a representative spring water of the region.
The History and Cultural Background of Daishomizu
Water Use Since the Edo Period
Kashomai’s Daishomizu has been used as a valuable water source for local residents since the Edo period. Kanazawa flourished as a castle town of the Kaga domain with one million koku of rice production, and abundant groundwater resources supported its development. Daishomizu also played an important role in sustaining the lives of the people in this region.
A Center of Community
In the past, Daishomizu was not merely a water-drawing place but also a social gathering space for local residents. It was an essential location for daily life—for washing clothes, cleaning vegetables, and securing drinking water—where human interactions and exchanges naturally emerged. Even today, cleaning activities and management by local residents continue, and the spring functions as a place that deepens community bonds.
Connection to the Kantaro River
The water flowing from Kashomai’s Daishomizu forms a small stream called the “Kantaro River.” This river has functioned as a waterway in the region and has been used for agricultural water and domestic water purposes. While there are various theories about the origin of the river’s name, it has become an important element that tells the story of the region’s history.
Water Quality and Characteristics of Daishomizu
The Spring Water Mechanism
The water source of Kashomai’s Daishomizu is rainwater that falls on the hills in the eastern part of Kanazawa City, which permeates underground and, over many years, passes through geological strata before emerging at the surface. During this process, the water is naturally filtered and appears in a clean state.
The geology of Kanazawa City consists mainly of Tertiary and Quaternary layers, with highly permeable sand and gravel layers promoting the storage and flow of groundwater. The Kashomai district has a relatively low elevation and a basin-like topography, with favorable geographical conditions for groundwater flowing from surrounding highlands to accumulate.
Water Temperature and Quality
The water temperature of Daishomizu remains nearly constant throughout the year, feeling cold in summer and relatively warm in winter. This is a characteristic unique to groundwater, as it is less affected by external temperature changes. Generally, groundwater temperature is close to the annual average air temperature, and in Kanazawa’s case, it is stable at approximately 14-16 degrees Celsius.
Regarding water quality, the water tends to be soft to medium-hard water containing an appropriate amount of minerals such as calcium and magnesium. With high transparency and no distinctive odor, it was once used as drinking water.
Fluctuations in Spring Water Volume
The volume of spring water from Daishomizu fluctuates depending on rainfall and seasons. The spring water volume tends to increase after the rainy season and autumn monsoons, while decreasing during dry periods. However, it is also said that as urbanization has progressed and paved surfaces have increased, the amount of rainwater infiltrating underground has decreased, leading to an overall declining trend in spring water volume compared to the past.
The Present State of Daishomizu
A Miraculous Space Appearing in a Residential Neighborhood
Visitors encountering Kashomai’s Daishomizu for the first time are often astounded by its location. The water place that suddenly appears in a corner of a residential neighborhood is truly a “kill on first sight” kind of miraculous space. Surrounded by residences yet possessing a unique atmosphere, the spring water pool and its surroundings represent a valuable natural space within the city.
Facility Structure
The water place of Daishomizu has a pond-like structure to receive water flowing from the ground. It is equipped with a concrete water tank divided into multiple sections. This design allows for different uses of water, making it possible to use the water separately for drinking, washing clothes, vegetable cleaning, and other purposes.
The water constantly overflows, flowing downstream through drainage channels. This circulation ensures a continuous supply of fresh water.
Management by Local Residents
Even today, Daishomizu is carefully managed by local residents. Regular cleaning activities are conducted to maintain the cleanliness of the water place. Furthermore, during community events and occasions, Daishomizu often becomes the center of conversation, serving as a symbol of local identity.

The Spring Water Culture of Ishikawa Prefecture and the Position of Daishomizu
Representative Spring Waters of Ishikawa Prefecture
Ishikawa Prefecture is a region blessed with abundant water resources, and from Kaga to Noto, many named waters exist. The Ministry of the Environment’s “Heisei Selection of 100 Famous Springs” includes “Kobo Pond Water (Hakusan City),” “Kowa Shomizu (Nanao City),” and “Sakura Shomizu (Wajima City)” from Ishikawa Prefecture.
Although Kashomai’s Daishomizu was not selected for the 100 Springs, it is one of the most well-known springs in Kanazawa City and exists as a special “living famous water” closely integrated with local life.
Kanazawa’s Water Culture
Kanazawa is also called the “City of Water,” and its abundant groundwater resources supported the development of the castle town. During the feudal period, irrigation channels were laid throughout the area, and historic waterways such as Tatsumi Aqueduct and Ohno Sho Aqueduct remain today.
Daishomizu plays a role in this water culture of Kanazawa and, even as modernization progresses, has become a precious place preserving traditional forms of water use.
Efforts to Protect Daishomizu
Community Conservation Activities
Residents of the Kashomai district recognize Daishomizu as a precious community resource and work to preserve it. In addition to regular cleaning activities, it is also utilized as a venue for environmental education for children.
Centered on neighborhood associations and community councils, maintenance and management of the water place and surrounding environment are carried out, and these steady efforts preserve the beauty of Daishomizu.
Kanazawa City’s Efforts
From the perspective of natural environment protection, Kanazawa City positions spring waters within the city as important resources. Daishomizu is also introduced on the official Kanazawa City website, helping to disseminate its value widely.
Furthermore, in urban planning, care is taken regarding development around spring water areas, and efforts continue to minimize impacts on groundwater veins.
Future Challenges
There is concern that the groundwater recharge function may decline as urbanization progresses. Increased paved surfaces hinder rainwater infiltration underground, potentially leading to decreased spring water volume in the long term.
In response to these challenges, initiatives are needed to realize sustainable water circulation, such as installing rainwater infiltration facilities and preserving green spaces.
