Maruike Spring Water: One of Japan’s 100 Famous Waters and a Source That Supports Daily Life
Maruike Spring Water (Maruike Yūsui) is a pond in Koba, Yūsui Town, Aira District, Kagoshima Prefecture, where groundwater from the foothills of the Kirishima Mountains rises to the surface.
It is both a sightseeing spot where visitors can admire the crystal-clear water and a carefully protected source that supports daily life in the Kurino area.
Selected as One of Japan’s 100 Famous Waters in 1985
In 1985, Maruike Spring Water was selected by Japan’s Ministry of the Environment as one of the country’s 100 Famous Waters.
This valuable spring at the foot of the Kirishima Mountains is used for the public water supply, irrigation, and everyday household needs.
Rather than viewing “famous water” only in terms of beautiful scenery, it is important to recognize the spring as water connected to local life and conservation efforts.
A Pond Producing About 60,000 Tons of Water per Day
Maruike Spring Water produces about 60,000 tons of water each day, at a temperature of approximately 18°C.
Water wells up as if pushing through the clear pond’s sandy bottom, then flows from the pond into channels.
Look closely at the pond floor and you can imagine where the water emerges, revealing something you would miss by watching only the surface.
Used as Daily Water for the Kurino Area
The spring water is used for everyday needs across almost the entire Kurino area.
It supplies more than 90% of the former Kurino Town, showing how deeply the spring is tied to daily life.
Visitors should remember that they are being allowed to see an essential water source and take care not to pollute the pond or channels.
Rain on Mt. Kurino Takes About 35 Years to Emerge as Spring Water
The clear water of Maruike Spring Water is not rain that has simply fallen on the ground and flowed straight into the pond.
Learning about its long journey beneath this volcanic region helps you sense the years contained in every drop before you.
Rain Falling at an Elevation of About 600 Meters
The water begins as rain falling around the 600-meter elevation of Mt. Kurino.
The rainwater seeps underground and travels through layers of earth toward Maruike.
Because water stored by the mountain emerges in the center of town, Maruike also connects the nature of the Kirishima foothills with local life.
About 35 Years Flowing Underground
It takes about 35 years for the rain to reappear above ground as Maruike Spring Water.
When you consider that the water you see during your visit has spent many years underground, the constantly flowing spring takes on a different meaning.
Even during a short visit, take a quiet moment to appreciate the long timescale of the water cycle.
Honoring the Water Deity and Protecting the Spring as a Community
Efforts to protect the water have continued since long ago, and a water deity is enshrined at the source.
Local residents also carry out cleanups, with everyday care helping preserve both the water quality and the scenery.
Visitors can contribute in a basic but meaningful way by avoiding unnecessary contact with waterside facilities and plants and by taking their trash home.
Top Things to See at Maruike Spring Water: The Surface, Sandy Bottom, and Channels
Rather than viewing the pond from only one direction, compare the light, the movement of the water, and the surrounding trees to discover its appeal.
Shift your gaze from the pond toward the channels to trace how the spring water flows into the town.
Crystal-Clear Water That Changes Color with the Light
The surface of Maruike appears blue or green depending on the brightness of the sky and the position of the shade from the trees.
Clear skies are not the only good time to visit; on cloudy days, the shapes of the pond floor and aquatic plants may be easier to see.
Do not rush to take a single photo. Change where you stand and the angle of your view to look for differences in reflection and clarity.
Spring Water Rising from the Sandy Bottom and a Stone-Paved Path
On the pond’s sandy floor, the emerging water creates subtle movement, revealing a current beneath the calm surface.
Continue from the pond along the channels, and you can watch the clear stream while walking on a stone-paved path.
The waterside can be wet and slippery, so do not walk while looking at a screen; stop before taking photos.
Seasonal Scenery with Cherry Blossoms and Fireflies
Maruike Spring Water can be visited year-round, but the plants and wildlife around it change the character of the waterside with the seasons.
Do not assume that flowers will bloom or wildlife will appear on a particular date; respect the weather and natural conditions of that year.
See Cherry Blossoms Surrounding the Water in Spring
In spring, cherry trees bloom around the pond, letting you enjoy the flowers and the water together.
Looking through the branches adds depth to the view, while walking toward the channels brings the rows of cherry trees and flowing water into the same scene.
Even during cherry blossom viewing season, keep the paths clear and make sure no trash, food, or drinks enter this source of daily water.
See Fireflies by the Water in Early Summer
Fireflies can be seen around Maruike in early summer.
If you observe them at night, do not shine strong lights toward the water. Keep the surroundings quiet and watch your footing in the dark.
Firefly numbers and viewing dates depend on natural conditions, so do not expect a guaranteed sighting; instead, appreciate the season by the water.
A Local Event Giving Thanks for the Famous Water
Each year in early September, Maruike Spring Water hosts Meisui Maruike Kansha no Yūbe, an evening event expressing gratitude for the gift of water.
The glow of about 3,000 bamboo lanterns illuminates the pond and its surroundings, creating a scene unlike the transparent water seen during the day.
Event details and dates vary by year, so check Yūsui Town’s event information if the gathering is the purpose of your visit.
Respect the Water Source While Collecting Water and Walking
Maruike Spring Water has a designated water-filling area, but the pond itself is not a place to enter and collect water.
Whether sightseeing, taking photos, or filling containers, remember that you are being allowed to use a shared community resource.
Use the Designated Water-Filling Area
If you want to take water home, use the designated filling area and do not place containers directly in the pond or channels.
When it is busy, do not occupy the space by lining up many containers; take turns with people who are waiting.
Prepare clean containers in advance, and check whether spilled water has made the ground slippery.
Do Not Damage the Pond, Channels, or Plants
Even if you want a closer look at the clear water, do not cross fences or step into the channels.
Do not move plants or stones, do not catch wildlife, and observe from the walkway.
An application is required to occupy or use the park, so contact Yūsui Town about photo shoots or events that go beyond an ordinary visit.
How to Get to Maruike Spring Water and Explore on Foot
Maruike Spring Water lies in the center of town and is easy to reach on foot from the train station.
If you visit by car, watch for pedestrians and local roads around the pond and move through the area calmly.
A Few Minutes on Foot from JR Kurino Station
The nearest station is Kurino Station on the JR Hisatsu Line, just a few minutes away on foot.
You can use the station’s public passageway to head toward the Maruike side, so check the signs after you arrive.
Train frequency and service conditions vary by day, so check your return time in advance as well as your outbound trip.
About 5 Minutes by Car from Kurino Interchange
Maruike Spring Water is about a 5-minute drive from Kurino Interchange on the Kyushu Expressway.
Parking is available, but when it is crowded, avoid parking illegally on the street and follow local guidance.
Water-filled containers become heavy, so choose an amount that matches your strength and secure them so they do not tip over in the car.
Walk Out and Back Along the Water Channels
After viewing the source and surface from around the pond, continue to the stone-paved path beside the channels to follow the direction in which the water flows.
Viewing the pond from different angles on the way out and back makes it easier to notice changes in color created by light and shade.
Even on a short walk, seeing the pond, the channels, and the setting of everyday life in that order helps you understand the role of Maruike Spring Water more fully.
Maruike Spring Water Highlights and Visitor Etiquette
At Maruike Spring Water, you can enjoy the transparent surface recognized among Japan’s 100 Famous Waters, the movement of water rising from the sandy bottom, the stone-paved channel path, and seasonal cherry blossoms and fireflies.
Knowing that rain falling on Mt. Kurino takes about 35 years to emerge and become water for the local community reveals both the scenery and the life it supports.
Use the designated area to fill containers, do not enter the pond or channels, and choose a practical route from JR Kurino Station or Kurino Interchange.
