八釜の甌穴群, Natural formation in Kochi Prefecture, Japan
The Yagama Giant's Kettles are a group of about 35 cylindrical holes carved into the riverbed rock. These depressions were created through the spinning motion of stones in flowing water, with some reaching depths of up to 14 meters.
These natural formations developed over thousands of years through repeated rotation of stones in the waters of the Kurokawa River. The process of stone wear and rock erosion gradually shaped the streambed into its present form.
The site received designation as a Special Natural Monument of Japan due to the exceptional concentration of multiple potholes in a single location.
Access is gained through a forest walking path near Route 440, which requires appropriate footwear. The walk takes about 40 minutes and can be slippery in wet conditions, so caution is needed on rocky surfaces.
The largest kettle has a diameter of about 9 to 12 meters and is filled with clear blue-green water year round. This distinctive feature makes it a photogenic highlight for visitors wanting to see the contrast between dark rock and glowing water.
