This is a fun and unique experience for the quirky everyday life attraction.

Hot spring water pump!

For just 10 yen per 10 liters, visitors can fill up their tanks with this alkaline sulfur hot spring water, known for its therapeutic properties like relieving muscle and joint pain. It's a popular spot for locals and even those who travel from afar to experience the rejuvenating effects of this natural spring water.

While you might not want to take 10L of hot spring water home, it's a fun location to visit and see for yourself. When I lived in Ueda I would collect the water for my home foot bath and I also used this for cooking as it is said to flavor vegetables.
