The spring water originates from melting snow and rain on Mt. Fuji, filtered through volcanic basalt layers for decades before emerging here.
The water temperature remains constant year-round, typically hovering around 15 degrees Celsius.
The park was built on the grounds of a former paper mill, and visitors can still see remnants of the old industrial pump systems.
Kakita-gawa is one of the shortest rivers in Japan, measuring approximately 1.2 kilometers in total length.
The springs were designated as a National Natural Monument in 2016 for their geological and ecological significance.
The deep blue color of the spring pools is caused by the light reflection off the volcanic sediment at the base of the wells.
The river serves as an important habitat for the Ayu (sweetfish) which migrate upstream to spawn.
The park features a dedicated 'Water Museum' or information center that explains the geological process of the aquifer.
Kakita-gawa Springs is a protected park built around the headwaters of the Kakita River, which is fed entirely by groundwater from Mt. Fuji. The site features multiple 'waki-ma' (spring pools) where water bubbles up through blue-tinted volcanic sand from underground aquifers. It is recognized as one of the 'Three Famous Waters' of Japan, discharging approximately one million tons of water daily at a constant temperature of 15 degrees Celsius. The park contains a series of elevated wooden boardwalks and observation decks that hover above the spring ponds and the river's upper reaches. These pathways provide direct views into the crystal-clear water, revealing aquatic plants like the watercress-like Mishima-baikamo. The park is a designated National Natural Monument of Japan. It previously served as the site of a defunct spinning factory, whose former water pipes are still integrated into the park's landscape. The surrounding riparian forest supports a variety of local flora and provides a shaded microclimate along the riverbanks.
The main observation deck overlooking the deepest 'waki-ma' spring pool for a view of the vibrant blue sand.
Bring a water bottle to fill up at the designated spring water tasting taps near the entrance.
Stick to the marked wooden boardwalks to avoid disturbing the fragile riverbank vegetation.
Visit the second observation deck, as it provides a clearer, deeper view of the bubbling spring 'wells'.
Do not attempt to walk into the river or climb over the railings to reach the water surface.
Stay on the designated boardwalks at all times; do not enter the water or touch the spring pools.
