About this location: Niko-buchi
Nikobuchi is a mystical pool upstream on the Edagawa River in the Niyodo River system. When sunlight hits the water, it glows in 'Niyodo Blue' — jade to cobalt. Locally considered sacred (home to a water deity), swimming and eating are prohibited.
Key features
- Niyodo Blue waters — deepest blue around midday on clear days; a polarizing filter further intensifies the color by cutting reflections
- Steep stairs (about 10 minutes) — over 100 slippery stone steps from the parking lot; non-slip footwear is essential
- Surrounding nature — the headwaters of the Niyodo, mossy boulders, primeval forest; mist and moss after rain are otherworldly
- Photography rules — be considerate with tripods when busy, no underwater photography, drones prohibited; respect local protocols
- Access difficulty — about 1 hour by car from Kochi City; nearest station is Tosa Kure, with a rental car strongly recommended
