Renowned for having the clearest waters in Japan, Kochi Prefecture’s Niyodo River and Shimanto River offer breathtaking vistas of pure streams and untouched nature that soothe the soul. Each river reveals its own unique character—from the vivid sapphire hues of “Niyodo Blue” to the gentle, meandering flow of the Shimanto.
This 3-day, 2-night model itinerary invites travelers to slow down and reconnect with the natural world. Starting from Kochi City, the journey immerses you in the serene beauty and healing presence of these two iconic rivers—each a living symbol of Japan’s unspoiled countryside and water-loving spirit.
Day 1: From Kochi City to the Headwaters of the Niyodo River – Immersing in the Mystical “Niyodo Blue”
Your journey begins at Kochi Ryoma Airport or JR Kochi Station. Before setting out, enjoy a taste of local flavors—Katsuo no Tataki (seared bonito) and other specialties from Tosa cuisine. Then, rent a car and head upstream to the Niyodo River, about 90 minutes from the city. One of the most iconic spots to witness the fabled Niyodo Blue is Nikobuchi, a hidden pool where sunlight transforms the water from emerald green to deep sapphire—a breathtaking display of clarity and color.
The area is dotted with scenic valleys like Nakatsu Gorge and Yasui Gorge, offering streamside walks in summer, vibrant foliage in autumn, and quiet stillness in winter. For the night, stay at a riverside hot spring inn or a traditional farmhouse-style guesthouse. Falling asleep to the sound of flowing water is a quiet luxury that only nature can provide.
Day 2: From the Niyodo to the Shimanto River – Immersed in River Life and Nostalgic Scenery
On your second day, leave the Niyodo behind and journey about two hours by car to the middle reaches of the Shimanto River—often called the “last clear stream of Japan.” Surrounded by lush greenery and flowing waters, the drive itself becomes part of the travel experience.
Once there, explore the iconic Sada Chinkabashi and Iwama Chinkabashi, low-water crossings known for their lack of railings. These simple, practical bridges, designed to sink under floodwaters, speak to the region’s harmony between daily life and nature—invoking a quiet nostalgia and profound beauty.
The Shimanto also offers a wide range of water activities such as canoeing and stand-up paddleboarding. Many beginner-friendly tours are available, making it a welcoming experience for families, couples, or solo travelers alike. Floating gently on the river, gazing up at the vast sky and forested hills, you’ll feel completely in tune with the rhythm of the natural world.
Spend the night in Shimanto Town or Shimanto City, where riverside inns serve local cuisine featuring river fish and seasonal vegetables. As you relax with a glass of local shochu or sake in the evening breeze, you’ll feel the quiet joy that only a journey like this can bring.
Day 3: Downstream Shimanto to Kochi – A Final Day Embracing the Flow of Water
On your final day, explore the lower reaches of the Shimanto River. In the Nakamura area, enjoy a serene riverboat ride, stroll along peaceful riverside paths, or visit the historic Ichijo Shrine. The slow-paced life of the people who live alongside the river, and the quiet charm of the waterside townscape, leave a lasting impression.
If time permits, stop by a michi-no-eki (roadside station) to discover local specialties and handcrafted goods. From yuzu citrus and Niyodo green tea to river-sourced delicacies and artisanal products, these souvenirs offer a perfect way to bring a piece of your journey home.
For your return, take the limited express train from Nakamura Station or Sukumo Station back to Kochi, or fly from Kochi Ryoma Airport. These three days, guided by the purest waters of Japan, will not only fill your eyes with beauty—but gently restore your inner rhythm as well.
Three Days of Clarity with Japan’s Purest Waters
From the mystical blue hues of Niyodo Blue to the gentle, meandering flow of the Shimanto River, this journey invites you to experience the distinct personalities and raw power of Japan’s sacred streams. It’s more than sightseeing—it’s a water retreat that nurtures the senses and calms the soul.
Wrapped in the soothing sound of flowing water, far from the noise of daily life, each moment spent in this natural sanctuary becomes a quiet imprint on the heart—an unforgettable immersion in purity and peace.
