Niko Deep / Nikobuchi, Mountain river pool in Ino Town, Japan
Niko Deep is a natural pool in the Niyodo River where water cascades down and pools in a crystal-clear basin. The water appears in shades of blue that shift with the light throughout the day.
The Niyodo River system has shaped the landscape and local communities over many centuries. This waterway became an important part of how people in the region developed and lived.
Local people view this place as spiritually important, which is why swimming is not permitted here. The respect for this belief shapes how visitors experience the site.
A paved walkway and metal stairs lead down from the main road to the water, making access straightforward and safe. The site is situated about an hour from major expressway access points, so plan travel time accordingly.
The water displays a special shade of blue that shifts throughout the day as the sun moves across the sky. This color comes from how light passes through the water and interacts with minerals in the river.
