Maruike Spring is a beautifully clear pond formed by rainwater that falls on the Kirishima mountain range and is slowly filtered through the earth over many years before bubbling up to the surface.
Its water is so transparent it looks like glass—you can clearly see the stones and aquatic plants on the bottom, making it a truly mesmerizing sight.

The fresh spring water is also used as a source of daily life for the local community. A water collection spot is set up nearby, and visitors often come to fill their containers with the clean, natural water.

A walking path surrounds the pond, offering a peaceful place to take a leisurely stroll and enjoy the gentle touch of nature.
Close by, you’ll also find the Yusui Town “Water Station” and shops selling local specialties, making it a popular spot to stop and relax during a sightseeing trip.

In spring, cherry blossoms bloom around the area, and in early summer, you can even see fireflies dancing in the evening light.

Recognized as one of the “Top 100 Famous Waters of Japan” by the Ministry of the Environment, Maruike Spring is a tranquil and beautiful retreat.
If you’re looking for a moment to reset your mind and soul, this is the perfect place to visit.
