About Izume Spring｜Basic Information and History
Overview of Izume Spring
Izume Spring is a spring water site located at 3934 Kobuchiuzawa Town, Hokuto City, Yamanashi Prefecture. Positioned in the rich forest area at the southern base of the Yatsugatake mountains, it sits at an elevation of approximately 900 meters. The greatest feature of this spring is that water springs forth from the roots of a massive fir tree over 500 years old.
Designated as a Yamanashi Prefecture Natural Monument as the “Kobuchiuzawa Fir,” this giant tree boasts an overwhelming presence with a height of approximately 40-50 meters and a trunk circumference of 5.85 meters. Standing distinctly tall among the trees, its appearance is truly worthy of being called a “sacred tree.”
The Origin of the Name and Its Position in the Region
The place name “Izume” is derived from the ancient local designation (koaza) for this area. It is believed that the name came about because the spring has supplied water to local people like a “well” (i).
Locally, it is also affectionately known as “Shono-no-ki-san,” but Izume Spring itself exists as a relatively quiet place—a mysterious destination known only to a few. While introduced as a tourist spot managed by the Japan Tourism Association (now the Yamanashi Tourism Promotion Organization), it has not been developed into a large-scale tourist attraction, and its natural state has been preserved.
The Mechanism of Spring Water and Water Quality
The southern base of the Yatsugatake mountains is known as one of Japan’s most abundant spring water areas, alongside Mount Fuji. Izume Spring is also formed by rain and snow that fall on the Yatsugatake mountains, seep underground over many years, pass through volcanic rock and lava layers, and become clear water through natural filtration before emerging at the surface.
Water springing forth from the unique location of a giant fir tree’s roots maintains stable temperatures year-round—cold in summer and resistant to freezing in winter. While water volume fluctuates seasonally, water continues to flow steadily throughout the year.
※Natural spring water is safer when boiled before drinking. If consumed directly at the site, it is at your own risk, so please note this precaution.
The Charm of the Prefecture-Designated Natural Monument “Kobuchiuzawa Fir”
The Overwhelming Presence of the Giant Tree
The greatest attraction when visiting Izume Spring is undoubtedly the “Kobuchiuzawa Fir,” designated as a Yamanashi Prefecture Natural Monument. This giant tree, over 500 years old, serves as a living witness to history spanning the Sengoku through Edo periods.
The tree reaches a height of approximately 40-50 meters, towering distinctly above other trees in the forest. Its trunk circumference of 5.85 meters is so thick that it takes several adults holding hands to barely encircle it. Looking up at it, you will surely be overwhelmed by its grandeur.
The Ecology and Characteristics of Fir Trees
The fir tree (momi) is an evergreen coniferous tree of the Pinaceae family, endemic to Japan. It naturally grows primarily on the mountains of Honshu, Shikoku, and Kyushu, particularly in cool-temperate forests at elevations of 700-1,800 meters.
The Kobuchiuzawa Fir has survived more than 500 years because the regional climate conditions were suitable for its growth. Fir trees grow relatively slowly as a species, but they have long lifespans and can live for several hundred years or more in appropriate environments.
Sacred Tree Reverence and Shrine
A small shrine is built at the roots of the giant fir tree, revealing that this tree has long been revered as a “sacred tree” by local people. Combined with the mystical atmosphere of the forest, it has also gained attention as a spiritual power spot.
In front of the shrine, visitors can be seen praying for safety and health. It remains an important place where people express reverence and gratitude toward nature.

Highlights and Ways to Enjoy Izume Spring
Natural Beauty Throughout the Four Seasons
Izume Spring displays a different face with each season.
Spring (April-May):

Winter (December-March):
Against a snowy backdrop, the giant fir tree exudes an even more mystical atmosphere. Since the spring water resists freezing, you can see water flowing even in winter. However, access may become difficult during heavy snowfall.

Yamanashi Prefecture’s Spring Water Culture and the Position of Izume Spring
Yamanashi Prefecture is a “Treasure House of Famous Waters”
Yamanashi Prefecture is an inland prefecture surrounded by mountains including Mount Fuji, the Southern Alps, and the Yatsugatake range, blessed with abundant spring water flowing from these mountains. Called “a land of famous waters chosen by heaven,” Yamanashi Prefecture has 7 locations selected for the Ministry of the Environment’s “Hyaku Sensui” (Hundred Famous Springs), ranking among the top spring water areas nationwide.
The Spring Water Group at the Southern Base of Yatsugatake
The area where Izume Spring is located, at the southern base of Yatsugatake, is particularly rich in spring water. Volcanic geology, abundant precipitation, and appropriate elevation changes create ideal conditions for producing high-quality spring water.
Hokuto City is home to springs such as “Sanbuichi Spring” and “Metori Spring,” which have been selected for the Hundred Famous Springs, and spring water pilgrimage routes are popular tourist attractions. While Izume Spring was not selected for the Hundred Famous Springs, it has become a little-known treasure with a unique landscape formed by its integration with the prefecture-designated natural monument fir tree.
Local Life and Spring Water
Since ancient times, communities at the southern base of Yatsugatake, including Kobuchiuzawa Town, have utilized spring water for daily life. As agricultural water and drinking water, springs have supported people’s livelihoods and are deeply connected with local culture and beliefs.
The shrine at the roots of the fir tree at Izume Spring is a manifestation of traditional local reverence and gratitude toward water.
Conclusion: Experiencing the Mystique of Nature at Izume Spring
Izume Spring is a mystical natural site where a giant fir tree over 500 years old, designated as a Yamanashi Prefecture Natural Monument, and clear water springing from its roots create a harmonious landscape. Despite its convenient location near the Yatsugatake Outlet Mall, this precious place offers visitors healing and inspiration in a quiet forest where they can feel the breath of nature.
Precisely because it has not been developed into a large-scale tourist attraction, its natural state remains preserved; the history and culture maintained by local people; and the beautiful landscape that changes with the seasons—Izume Spring possesses the charm of conveying “harmony with nature,” something increasingly lost in modern society.
When visiting the Yatsugatake area or Kobuchiuzawa, please take a slight detour to visit Izume Spring. The overwhelming presence of the giant fir tree and the clear water springing from its roots will surely provide you with an unforgettable experience.
As visitors, it is our responsibility to honor nature, protect the environment, and pass this precious natural heritage on to future generations.
