Bumon-in Temple and Sumigokoro Spring | Historic Temple Associated with Lord Uesugi Takayama
Bumon-in Temple, where Sumigokoro Spring gushes, is a nationally designated historic site in Yonezawa City and is known as a place associated with Lord Uesugi Takayama, a renowned wise ruler of the Edo period.
History of Bumon-in Temple
Bumon-in Temple has a long history and was also one of the bases of spiritual culture that Lord Uesugi Takayama, the Yonezawa clan lord, valued as part of his domain reforms. The temple grounds feature the main hall and historic structures of high cultural value such as Kintendo Yakushi Hall, creating beautiful scenery with plants and trees that change with the seasons.
Kintendo Yakushi Hall (Korori Yakushi) and Its Relationship with Sumigokoro Spring
Kintendo Yakushi Hall, which stands where Sumigokoro Spring gushes, has the alternate name “Korori Yakushi.” While there are various theories about the origin of this name, a legend has been passed down that when an epidemic once raged, people prayed to this Medicine Master and avoided illness by drinking the water from Sumigokoro Spring.
For this reason, local residents call Sumigokoro Spring the “Medicine Master’s Water,” and have continued to protect it carefully not only as an object of faith but also as a precious water resource in their daily lives. This connection between water and faith is an example that symbolizes the spirituality in Japanese water culture.
The Geological Mechanism of Sumigokoro Spring | Why It Never Runs Dry
The reason Sumigokoro Spring is called “mysterious water” lies in its gushing mechanism.
Groundwater System and Recharge Area
The geological structure around the Yonezawa Basin has complex underground water veins flowing from the Azuma and Iide mountain ranges. Although the hillside where Sumigokoro Spring is located appears to have no streams or pools as water sources, a vast mountainous area actually serves as a recharge area (a region that stores groundwater), with precipitation and snowmelt seeping deep underground.
Natural Filtration System Through Rock Formations
Water that seeps underground passes through rock formations and gravel layers over tens to hundreds of years. Through this process, impurities are removed, and the water becomes clear water containing an appropriate amount of minerals. The expression that Sumigokoro Spring’s water is “drawn up by stones” represents an intuitive grasp of this natural filtration system.
The Secret of Stable Spring Water Volume
The fact that Sumigokoro Spring has never run dry indicates that the groundwater system behind it is extremely stable. A vast recharge area and deep aquifer ensure a water source that is not easily affected by seasonal variations or changes in rainfall.
