History of Gunminzaka Spring Water | The Showa Depression and Agricultural Relief Civil Engineering
The birth of Gunminzaka Spring Water has deep connections to the socioeconomic conditions of the early Showa period. Understanding this history clarifies the spring water’s value as a local cultural asset.
Road Improvement Project of 1935
Gunminzaka Spring Water began flowing in its current form in Showa Year 10 (1935). At that time, road improvements were planned as part of agricultural relief civil engineering to aid rural areas suffering from the Showa Depression.
This project was implemented through cooperation between the former Imperial Army Mito Engineer Unit Fourteen (under Captain Takasaku Nishimura and thirty subordinates) and local residents. Because the military and civilians cooperated, Captain Nishimura renamed the slope “Gunminzaka” (Military-Civilian Slope), a name that has been passed down to the present day.
Bedrock Blasting with Dynamite
In carrying out the road improvements, it was necessary to modify the old road (Kamei Slope) that had been blocked by steep terrain. Day after day, bedrock blasting with dynamite was conducted, and these efforts were recorded in local documents as “magnificent.”
This blasting work altered the underground water vein, causing new spring water to emerge midway along the slope, creating the current Gunminzaka Spring Water. As a memorial to the construction, a monument bearing Captain Nishimura’s mark still exists, testament to its historical value.
Relationship with Mikuni Falls
Before Gunminzaka Spring Water was established, a waterfall known as “Mikuni Falls (Ōtaki)” with a drop of approximately four meters existed in this area. It is believed that as a result of the changed water vein caused by the road improvement project, water that had previously flowed to Mikuni Falls began gushing out midway along Gunminzaka Slope.
Part of Mikuni Falls still bears traces nearby, suggesting the former abundance of this water source. In this way, Gunminzaka Spring Water represents an interesting case of natural water sources changing form through human activity.
Water Quality and Drinking | Systematic Regular Testing
Since its birth, Gunminzaka Spring Water has been maintained and managed as domestic water by local residents. It currently maintains water quality suitable for drinking, and many people visit to collect water.
