Unveiling the Veil of “Niyodo Blue”: The Miraculous Color of Niko Buchi
The term “Niyodo Blue” was coined by nature photographer Mr. Nobuyuki Takahashi, who has been photographing the Niyodo River for many years, to describe the uniquely stunning clear blue color found in the Niyodo River basin. And Niko Buchi is one of the most representative locations that perfectly embodies this color.
Why So Deeply Blue and Clear?
The exact scientific reasons for the “Niyodo Blue” phenomenon at Niko Buchi and the Niyodo River are still being researched, but it is generally believed to be related to the following factors: Extremely High Water Purity: The Niyodo River has been repeatedly rated as one of the rivers with the best water quality in Japan. The water quality of its tributary, the Egawagawa, is equally very clear, with extremely few suspended impurities in the water. Optical Properties of Water: Pure water absorbs the red wavelengths of light and scatters the blue wavelengths. The purer and deeper the water, the more pronounced the visual effect of blue becomes. Low Water Temperature Inhibits Algae: The water temperature in the Niyodo River basin is relatively low, which is not conducive to the proliferation of algae, further maintaining the clarity of the water quality. Riverbed Geology: The rocks on the riverbed have high hardness and are not easily eroded by the water flow to produce fine silt and debris. Angle of Light: The angle and intensity of sunlight are key factors influencing the manifestation of “Niyodo Blue.” When sunlight can penetrate the water surface and reach the bottom of the basin, the blue color is most vibrant and moving. These factors work together to create the unique, dreamlike blue miracle of Niko Buchi. Its color subtly changes with light, time, and weather, and it is said that you will never see the exact same blue throughout the year.

This legend adds a layer of mystery to Niko Buchi and reminds visitors to approach with respect.

Journey to the Blue Secret Place: Transportation, Best Time, and Challenges
Niko Buchi is located in a relatively secluded mountain valley, and reaching it requires some physical effort, as well as attention to safety.
How to Get to Niko Buchi?
Main Method: Driving: The most convenient way to get to Niko Buchi is by driving. Navigation Settings: You can set your navigation to “にこ淵” or the nearby “Green Park Hodono” (グリーンパークほどの). Route: From downtown Kochi City, take National Route 194 towards Ino Town Hodowake. There will be signs along the way. Parking Lot: There is a free parking lot (approx. 20 spaces) before the trail entrance leading to the waterfall. Parking is limited, and you may need to wait during peak season or holidays. Please do not park randomly on the roadside. There are public restrooms near the parking lot. Public Transportation (Less Convenient): The nearest JR station is “Ino Station” (伊野駅, Ino Station). Taking a taxi from Ino Station to Niko Buchi takes about 50 minutes. Using buses is very difficult, with infrequent services and multiple transfers required, so it is not recommended.
Challenging Steep Stairs: The Path to the Waterfall Basin
Trail Entrance: From the parking lot, you need to walk down a trail to reach the edge of the waterfall basin. 【Important!】Steep and Slippery: This trail is very steep, mostly consisting of stairs with significant height differences (some are metal stairs, some are rock stairs), and because it is close to the water, it is often in a slippery condition. In the past, it even required descending by holding onto ropes. Although stairs have been built in recent years, it is still quite dangerous. The return journey is a continuous uphill climb, which will be very physically demanding. Required Time: Walking from the parking lot to the edge of the waterfall basin takes about 5-10 minutes one way, but due to the steep and slippery trail conditions, please be sure to walk slowly. Summary: Getting to Niko Buchi requires a certain level of physical fitness, and you must wear appropriate shoes and always pay attention to safety underfoot. It is not recommended for those with mobility issues or those wearing inappropriate footwear.
Best Time to Capture “Niyodo Blue”
Weather: Sunny weather is the primary condition for seeing the beautiful blue. Time: From morning to noon, especially the time when the sunlight can directly shine onto the bottom of the waterfall basin (approximately from 11:00 AM to around 1:00 PM, though it varies with the season), is when “Niyodo Blue” is most brilliant. Too early or too late, the sunlight will be blocked by the valley, and the water color will appear darker. Season: Spring/Summer (May-August): Fresh greenery, ample light, a good season to see the blue. Autumn (October-November): Autumn leaves contrast with the blue basin, making for beautiful scenery, but the angle of sunlight may not be as good as in summer. Winter: Water volume may be lower, but the water quality may be clearer. Need to be aware of road icing issues. Caution after rain: After heavy rain, you may have a chance to see the waterfall flow, but the basin water may also become turbid, affecting the presentation of the blue color.
Clothing and Safety Reminders
Shoes: You must wear hiking boots, trekking shoes, or amphibious shoes with good grip and slip resistance. High heels, sandals, slippers, or shoes with flat soles are strictly prohibited. Clothing: It is recommended to wear clothing that is easy to move in and that you don’t mind getting wet or dirty. Mountain temperatures can be lower, so bringing a jacket is recommended. Safety: Be sure to climb stairs slowly and carefully, holding onto handrails or using ropes (if available). The rocks around the waterfall basin are extremely slippery, so do not approach the edge of the basin or climb on the rocks. Beware of falling rocks. Cell phone signal may be unstable in mountain areas. Other: Drinking water, towel, camera (be mindful of waterproofing).
