The Rokugō Yūsui Group, which spans Misato Town in Senboku District, Akita Prefecture, is a rare spring water area throughout Japan where clear groundwater flowing from the Ou Mountain Range gushes forth from over 60 locations. In 1985 (Showa 60), it was selected as one of the “Top 100 Water Springs” by the Ministry of the Environment, and continues to captivate many people not only as a water source for local residents’ daily life but also as a tourism resource.
This article provides a complete introduction to the charm of the Rokugō Yūsui Group, covering its historical background, representative spring water spots, access methods, surrounding tourism information, and regional cuisine that makes use of the spring water.
What is the Rokugō Yūsui Group? Reasons for Selection as Top 100 Water Springs
Overview and Characteristics of Rokugō Yūsui Group
The Rokugō Yūsui Group is a collective term for spring water areas that spread primarily through the Rokugō district of Misato Town in Senboku District, Akita Prefecture. Groundwater originating from Waga-dake (elevation 1,440m) in the Ou Mountain Range naturally springs forth at various locations throughout the town. The total number of spring water locations exceeds 60, and the total daily discharge is said to be approximately 100,000 tons.
The water temperature of the springs remains nearly constant throughout the year, maintaining approximately 10-12 degrees Celsius. This stable water temperature, abundant water volume, and high water quality are the greatest characteristics of the Rokugō Yūsui Group. The water quality is extremely clear and suitable for drinking, and local residents have used it as daily water for ancient times.
Background of Top 100 Water Springs Selection
In March 1985 (Showa 60), the Environmental Agency (now Ministry of the Environment) selected “Top 100 Water Springs” for the purpose of preserving excellent water environments throughout Japan. The Rokugō Yūsui Group was successfully selected in this first round of designations, making it the only Top 100 Water Spring in Akita Prefecture.
The selection was evaluated based on the following points:
- Water Quality Excellence: Mineral-balanced water quality suitable for drinking with excellent clarity
- Abundant Water Volume: Stable discharge throughout the year
- Coexistence with Community: The point that residents cherish the spring water and utilize it in their daily lives
- Scenic Value: Beautiful scenery surrounding spring water areas and cultural value
- Historical Significance: History of use as a water source for the region since ancient times
History and Geological Background of Rokugō Yūsui Group
Geological Structure Creating Spring Water
The spring water mechanism of the Rokugō Yūsui Group stems from the geological structure unique to this region. Rain and snowmelt that fall on the Ou Mountain Range permeate underground through volcanic permeable layers. Subsequently, after traveling underground for extended periods while being filtered, the water is blocked by an impermeable layer in the Rokugō district’s alluvial fan and springs forth to the surface.
This natural filtration system results in spring water with few impurities and minerals in balanced proportions. The underground retention time is said to be several decades, meaning the water currently gushing forth is rain that fell several decades ago.
History of Rokugō District and Spring Water
Records remain showing that the Rokugō district has used spring water as daily water since before the Edo period. Particularly during the Edo period, sake brewing and soy sauce fermentation using spring water were actively conducted, serving as important resources supporting the regional economy.
After the Meiji period, spring water continued to be an indispensable resource for agriculture and daily water supply. Upon entering the Showa period, “water areas” managed by local residents were established at each spring water location, and a culture of jointly protecting spring water was established.
In modern times, many households continue to visit to draw spring water, using it for drinking water and cooking. This very culture of “living with spring water” is the greatest reason the Rokugō Yūsui Group has been preserved to this day.
