熊本県阿蘇郡高森町「高森湧水トンネル公園」

I walked through the Takamori Spring Water Tunnel in Takamori Town, Aso. Originally dug as a railway tunnel, plans to extend it were halted after a large amount of spring water gushed out during construction. It has now been developed into a spring water park. A river flows through the tunnel, and you can see facilities that make use of the spring water, such as seasonal exhibits, "Water Pearls," and micro-hydroelectric power plants. Note: During the scene from the "Micro Hydroelectric Power Plant" at the very end of the tunnel to the "Water Pearls," the screen will flicker due to lighting effects. Please be aware of this when watching.
