Kakidagawa Yusui Group Shizuoka Prefecture | Complete Guide to the Famous Water Spring with Oriental’s Largest Water Volume
Located in Shimizu Town, Sunto District, Shizuoka Prefecture, the Kakidagawa Yusui Group is one of Japan’s premier spring water sites where subterranean water from Mount Fuji emerges. With abundant water volume exceeding 1 million tons per day and highly transparent clear streams, it is also called “the largest in the Oriental region” and has been selected as one of Japan’s 100 Famous Waters and a Nationally Designated Natural Monument. This article provides a comprehensive introduction from the charm of the Kakidagawa Yusui Group to practical visitor information.
What is the Kakidagawa Yusui Group? An Overview of Shizuoka Prefecture’s Natural Monument
The Kakidagawa Yusui Group is a spring water site located in Fushimi, Shimizu Town, Sunto District, Shizuoka Prefecture, where subterranean water from Mount Fuji emerges. Water that springs forth directly beneath National Route 1 becomes the Kakidagawa River with a width of 30-50 meters, and merges with the Kano River just 1.2 kilometers downstream.
Reasons for Having the Largest Spring Water Volume in the Oriental Region
The greatest characteristic of the Kakidagawa Yusui Group is its overwhelming volume of spring water. Between 1 million and up to 1.5 million tons of water emerge daily, with this volume said to be the largest in the Oriental region. Spring outlets that spout water and sand are seen throughout the river, and this sight never ceases to captivate visitors.
The mechanism of the spring water involves rain and snow that falls on Mount Fuji infiltrating into the ground and flowing through the porous Mishima lava flow over many years. According to experts, the water that emerges originates from rain and snow that fell on Mount Fuji decades to over a hundred years ago.
The Value of Japan’s 100 Famous Waters and Nationally Designated Natural Monument
The Kakidagawa Yusui Group is a precious natural resource whose value has been officially recognized. The main designations include:
- Japan’s 100 Famous Waters (1985, selected by the Ministry of the Environment)

These designations testify to the value of the Kakidagawa Yusui Group in terms of natural environment, superior water quality, and rich ecosystems.
Water Quality and Characteristics of Kakidagawa Yusui Group
Consistent Water Temperature Throughout the Year
The spring water of the Kakidagawa River maintains a constant temperature of around 15°C year-round regardless of season. This stable water temperature results from the characteristics of subterranean water flowing through deep ground—cool in summer and warm in winter. This characteristic becomes a crucial element in nurturing the unique ecosystem of the Kakidagawa.
Ideal Drinking Water Rich in Minerals
The spring water of the Kakidagawa contains approximately 100mg of minerals per liter, possessing an ideal component balance as drinking water. The water quality is excellent, and it is used as a water source for approximately 410,000 people in Shimizu Town, Mishima City, Numazu City, and other municipalities, as well as for industrial water.
The high transparency allows the water emerging from the spring outlet to be clearly visible to the naked eye, and this clarity brings deep emotion to all who visit.
Scenic Viewpoints of the Spring Water Group at Kakidagawa Park
First and Second Observation Platforms
Two observation platforms are installed in Kakidagawa Park to observe the spring water group at close range.
From the First Observation Platform, you can look down from directly above at blue, transparent water emerging from a circular spring hole. This spring hole was once used as a well, and water surging from the bottom at a depth of approximately 4 meters while swirling up sand shines like a jewel.
From the Second Observation Platform, you can observe multiple spring holes gathered together. The volume and force of water emerging from each spring hole differ, making it a spot where you can feel the diversity of nature.
The view from the observation platform changes its expression depending on weather and light, offering new discoveries with each visit. Particularly on sunny mornings, sunlight filters through the water surface, making the blue of the spring water even more striking.
Experiencing the Clear Stream at the Spring Water Plaza
At the spring water plaza, you can actually step into the water and experience the coldness of the spring water. The water temperature of around 15°C even in midsummer provides a pleasant coldness to experience the blessings of nature through all five senses.
It is also popular with families with small children, and an environment for safe water play is established. However, since the water is extremely cold, it is recommended to avoid prolonged immersion and take breaks periodically.
Enjoying Natural Walks on the Walking Path
A walking path has been developed within Kakidagawa Park where you can enjoy nature walks while viewing the Kakidagawa, a Nationally Designated Natural Monument. Surrounded by lush greenery, the walking path displays different faces with each season.
In spring, fresh greenery is beautiful; in summer, the shade of trees creates a cool walking path; in autumn, you can enjoy crimson leaves; and in winter, the clear stream in crisp air. Along the walking path, you may encounter rare flora and fauna, making it ideal for nature observation.
The Rich Ecosystem of the Kakidagawa
Mishima Baika-mo (Mishima Umebana-so)
The representative plant of the Kakidagawa is Mishima Baika-mo. This aquatic plant thrives only in clear streams and is a precious species, producing small white flowers resembling plum blossoms. The Kakidagawa, with its constant water temperature and superior water quality, provides an ideal growing environment for Mishima Baika-mo.
The flowering period is mainly from May to September, and small white flowers swaying underwater further enhance the beauty of the clear stream. Mishima Baika-mo is sensitive to environmental changes, and its very presence testifies to the good water quality of the Kakidagawa.
Genji Hotaru (Genji Fireflies) and Kawasemi (Kingfisher)
The rich natural environment of the Kakidagawa serves as a habitat for diverse organisms. In early summer, Genji fireflies dance, creating a fantastical scene. The presence of fireflies proves good water quality and rich natural environment.
The kawasemi, called a jewel of clear streams, is also frequently observed. The kingfisher with its bright blue wings flying just above the water surface or perching on branches to hunt fish is popular with birdwatchers and photography enthusiasts.
Additionally, fish species such as sweetfish and loach, crustaceans such as mountain stream crabs, and various aquatic insects inhabit the area, making the Kakidagawa a treasure trove of precious ecosystems.
